release: version 0.10.4 (#3767)

The translate.toil.cc relay that backs the yandex provider is currently
unavailable. Introduce a `disabled` flag on TranslationProvider and
filter disabled providers out of both `getTranslators()` and
`getTranslator()` so the settings panel, translator popup, and the
fallback logic in `useTranslator` all agree the provider doesn't exist —
no per-callsite changes needed. Flip the flag back (or delete the line)
on `yandexProvider` to re-enable once the upstream is healthy.

+## Troubleshooting
+
+### 1. Readest Won’t Launch on Windows (Missing Edge WebView2 Runtime)
+
+**Symptom**
+
+- When you double-click readest.exe, nothing happens. No window appears, and Task Manager does not show the process.
+- This can affect both the standard installer and the portable version.
+
+**Cause**
+
+- Microsoft Edge WebView2 Runtime is either missing, outdated, or improperly installed on your system. Readest depends on WebView2 to render the interface on Windows.
+
+**How to Fix**
+
+1. Check if WebView2 is installed
+   - Open “Add or Remove Programs” (a.k.a. Apps & features) on Windows. Look for “Microsoft Edge WebView2 Runtime.”
+2. Install or Update WebView2
+   - Download the WebView2 Runtime directly from Microsoft: [link](https://developer.microsoft.com/en-us/microsoft-edge/webview2?form=MA13LH).
+   - If you prefer an offline installer, download the offline package and run it as an Administrator.
+3. Re-run Readest
+   - After installing/updating WebView2, launch readest.exe again.
+   - If you still encounter problems, reboot your PC and try again.
+
+**Additional Tips**
+
+- If reinstalling once doesn’t work, uninstall Edge WebView2 completely, then reinstall it with Administrator privileges.
+- Verify your Windows installation has the latest updates from Microsoft.
+
+**Still Stuck?**
+
+- See Issue [readest/readest#358](https://github.com/readest/readest/issues/358) for further details, or head over to our [Discord][link-discord] server and open a support discussion with detailed logs of your environment and the steps you’ve taken.
+
+### 2. AppImage Launches but Only Shows a Taskbar Icon
+
+On some Arch Linux systems—especially those using Wayland—the Readest AppImage may briefly show an icon in the taskbar and then exit without opening a window.
+
+You might see logs such as:
+
+```
+Could not create default EGL display: EGL_BAD_PARAMETER. Aborting...
+```
+
+This behavior is usually caused by compatibility issues between the bundled AppImage libraries and the system’s EGL / Wayland environment.
+
+**Workaround 1: Launch with LD_PRELOAD (recommended)**
+
+You can preload the system Wayland client library before launching the AppImage:
+
+```
+LD_PRELOAD=/usr/lib/libwayland-client.so /path/to/Readest.AppImage
+```
+
+This workaround has been confirmed to resolve the issue on affected systems.
+
+**Workaround 2: Use the Flatpak Version**
+
+If you prefer a more reliable out-of-the-box experience on Arch Linux, consider using the [Flatpak build on Flathub][link-flathub] instead. The Flatpak runtime helps avoid system library mismatches and tends to behave more consistently across different Wayland and X11 setups.

+# Annotator & Reader Fixes Reference
+
+## Annotation System Architecture
+
+### Key Components
+- `Annotator.tsx` - Annotation lifecycle, popup display, style/color management
+- `AnnotationRangeEditor.tsx` - Drag handles for adjusting selection range
+- `MagnifierLoupe.tsx` - Magnifying glass during handle drag (mobile only)
+- `useTextSelector.ts` - Text selection detection and processing
+- `useAnnotationEditor.ts` - Editing existing annotations
+- `useInstantAnnotation.ts` - Creating new annotations on selection
+
+### Highlight Rendering
+- Highlights rendered by foliate-js `Overlayer` (SVG overlayer in paginator shadow DOM, not iframe)
+- Each view in multiview paginator has its own `Overlayer` instance with unique clipPath ID
+- `Overlayer.add()` stores range + draw function; `redraw()` recalculates positions from stored ranges
+- Colors stored as color names mapped to custom hex via `globalReadSettings.customHighlightColors`
+- Sidebar uses `color-mix()` CSS function with custom colors, not Tailwind utility classes (#3273)
+- Rounded highlight style supported via `vertical` option passed to overlayer (#3208)
+
+### Multiview Overlayer Pitfalls
+- **Duplicate SVG IDs**: Each overlayer creates `<clipPath>` for loupe hole — IDs MUST be unique per instance or `url(#id)` resolves to wrong element, clipping everything
+- **docLoadHandler scope**: `FoliateViewer.tsx` re-adds annotations on `load` event — MUST filter by `detail.index` (loaded section), not re-add ALL annotations (overwrites drag edits)
+- **MagnifierLoupe lifecycle**: Don't destroy/recreate loupe on every drag tick — `hideLoupe()` should only run on unmount, `showLoupe()` fast path updates position only
+- **Stale closures in useTextSelector**: `getProgress()` must be called inside callbacks, not captured at hook top-level (useFoliateEvents deps are `[view]` only)
+
+## Fix History
+
+| Issue | Problem | Root Cause | Fix |
+|-------|---------|------------|-----|
+| #3286 | Selection stuck on first annotation | `initializedRef` guard blocked re-computation | Remove guard, consolidate style/color effects |
+| #3273 | Custom colors not in sidebar | Hardcoded Tailwind classes | Use inline `style` with `color-mix()` |
+| #3234 | Letter-by-letter selection on mobile | No word boundary snapping | Add `snapRangeToWords()` using `Intl.Segmenter` |
+| #3208 | Hard rectangular highlights | No border radius support | Pass `vertical` option, update foliate-js |
+| #3002 | Can't see text under finger | No magnification UI | New `MagnifierLoupe` component using `view.renderer.showLoupe()` |
+| #3082 | No page numbers on annotations | `pageNumber` field missing | Add `pageNumber` to BookNote type, compute on create |
+| #3225 | Android tools unresponsive | Premature `makeSelection()` call | Remove premature re-selection in Android path |
+
+## Common Annotation Bugs
+
+### Selection Issues
+- **Word snapping**: Uses `Intl.Segmenter` with `granularity: 'word'` to snap selection to word boundaries
+- **Android re-selection**: Don't call `makeSelection(sel, index, true)` immediately on pointer-up; let the popup flow complete
+- **Range editor handles**: Remove `initializedRef` guards that prevent re-computation when switching annotations
+
+### Color/Style Issues
+- **Custom colors in sidebar**: Use inline `style={{ backgroundColor: 'color-mix(...)' }}` not Tailwind classes
+- **Style synchronization**: Consolidate `selectedStyle` and `selectedColor` into one `useEffect`
+- **Switching annotations**: Must call `setShowAnnotPopup(false)` and `setEditingAnnotation(null)` before setting up new annotation
+
+## Reader/Content Fixes
+
+### Progress Display
+- Use physical `view.renderer.page` and `view.renderer.pages` for page counts (#3213, #3200)
+- Last page shows 100% by fixing boundary condition (#3383)
+- FB2 subsections need special handling for progress (#3136)
+
+### Translation View (#3078)
+- Problem: Page jumps back during full-text translation
+- Root cause: DOM mutations from sequential translation insertions cause paginator relayout
+- Fix: Batch DOM updates with 50ms timer, use bounded concurrent queue (max 5), show loading overlay
+
+### TOC Navigation (#3124)
+- Problem: Expanding TOC chapter scrolls back to current chapter
+- Fix: Only scroll-into-view on navigation, not on expand/collapse
+
+## Accessibility (a11y) Fixes
+
+### Screen Reader (TalkBack) Support
+- **Page indicator updates** (#2276): Add focus handlers on `<p>` elements that call `view.goTo(cfi)` to update position
+- **Navigation buttons** (#3036): Always show prev/next buttons when screen reader active; `PageNavigationButtons.tsx`
+- **Dropdown menus** (#3035): Use `DropdownContext` with overlay dismiss instead of blur-based closing
+
+### Dropdown Architecture for a11y
+- `DropdownContext` (`src/context/DropdownContext.tsx`) manages which dropdown is open globally
+- Uses `useId()` for unique identification
+- One dropdown open at a time
+- `<Overlay>` for dismissal (tap/click outside) instead of `onBlur`
+- `<details>` element with `open={isOpen}` for semantic structure
+- No auto-focus-first-item (conflicts with TalkBack)
+
+## E-ink Readability
+- Use `not-eink:` Tailwind variant for colors and opacity (#3258)
+- Don't use `text-primary` (blue) or low opacity on e-ink
+- Highlights use foreground color in dark mode e-ink (#3299)
+
+## Key Utility Functions
+- `snapRangeToWords()` in `src/utils/sel.ts` - Word boundary snapping
+- `handleAccessibilityEvents()` in `src/utils/a11y.ts` - Screen reader focus handling
+- `color-mix()` CSS function for custom highlight colors with opacity

+# Bug Fixing Patterns & Strategies
+
+## Common Root Cause Categories
+
+### 1. Overly Broad CSS Selectors
+**Pattern:** A CSS rule targets too many elements, causing unintended visual side effects.
+**Examples:**
+- `hr { mix-blend-mode: multiply }` applied to ALL hr elements instead of only decorative ones (#3086)
+- `p img { mix-blend-mode }` applied to block images, not just inline (#3112)
+- `svg, img { height: auto; width: auto }` overrode explicit HTML width/height attributes (#3274)
+- Background-color override applied unconditionally instead of only when user enabled color override (#3316)
+
+**Fix Strategy:** Narrow selectors with class qualifiers (`.background-img`, `.has-text-siblings`) or attribute pseudo-selectors (`:where(:not([width]))`). Check if the rule should be conditional on a user setting.
+
+### 2. Conditional vs Unconditional Style Overrides
+**Pattern:** CSS rules meant for "Override Book Color/Layout" mode are placed in the always-active stylesheet.
+**Examples:**
+- Calibre `.calibre { color: unset }` was in `getLayoutStyles()` instead of `getColorStyles()` (#3448)
+- Image background-color override applied without checking `overrideColor` flag (#3316, #3377)
+
+**Fix Strategy:** Move rules to the correct conditional block: `getColorStyles()` for color overrides, `getLayoutStyles()` for layout overrides. Check the `overrideColor`/`overrideLayout` flags.
+
+### 3. Missing EPUB Stylesheet Transformations
+**Pattern:** EPUB stylesheets contain CSS that conflicts with app functionality.
+**Examples:**
+- `user-select: none` prevents text selection (#3370) -> regex replace in `transformStylesheet()`
+- `font-family: serif/sans-serif` on body bypasses user font (#3334) -> detect and unset
+- Hardcoded Calibre backgrounds persist in dark mode (#3448) -> unset in color override
+
+**Fix Strategy:** Add regex-based transformation passes in `transformStylesheet()` in `style.ts`.
+
+### 4. Stale State / Refs Not Reset
+**Pattern:** A `useRef` or state variable is set once and never properly reset, blocking re-entry.
+**Examples:**
+- TTS `ttsOnRef` prevented restarting TTS from a new location (#3292)
+- `initializedRef` in AnnotationRangeEditor prevented handle position updates (#3286)
+- `view.tts` not nulled on shutdown prevented clean TTS restart (#3400)
+- TTS safety timeout fired after pause, advancing to next sentence (#3244)
+
+**Fix Strategy:** Check all refs/guards in the affected flow. Ensure cleanup in shutdown/unmount. Remove overly aggressive guards that prevent re-entry.
+
+### 5. Platform API Differences
+**Pattern:** A Web API behaves differently or is unavailable on certain platforms.
+**Examples:**
+- `navigator.getGamepads()` returns null on older Android WebView (#3245)
+- `CompressionStream` unavailable on some Android versions (#3255)
+- `btoa()` throws on non-ASCII characters (#3436)
+- View Transitions API unsupported in WebKitGTK/Linux (#3417)
+- `document.startViewTransition()` crashes on Linux
+
+**Fix Strategy:** Always check API availability before use. Add fallback paths. Use feature detection, not platform detection when possible.
+
+### 6. Safe Area Inset Issues
+**Pattern:** UI elements overlap system bars (status bar, navigation bar, notch) on mobile.
+**Examples:**
+- Zoom controls behind status bar (#3426)
+- Android navigation bar overlap (#3466)
+- iPad sidebar insets incorrect (#3395)
+- Reader page layout jump after system UI change (#3469)
+
+**Fix Strategy:** Use `gridInsets` and `statusBarHeight` from `useSafeAreaInsets`. Use `env(safe-area-inset-*)` CSS functions. Call `onUpdateInsets()` after system UI visibility changes. See `docs/safe-area-insets.md`.
+
+### 7. Z-Index Layering Issues
+**Pattern:** Interactive elements rendered behind other layers, becoming unclickable.
+**Examples:**
+- Navigation buttons invisible on mobile (#3201) -> added `z-10`
+- Annotation nav bar too prominent (#3386) -> reduced from `z-30` to `z-10`
+- Page nav buttons behind TTS control (#3184)
+
+**Fix Strategy:** Check z-index ordering. Use minimum necessary z-index. Reference the z-index hierarchy in the codebase.
+
+### 8. Event Handling Race Conditions
+**Pattern:** Timing issues between pointer events, native menus, and React state updates.
+**Examples:**
+- macOS context menu steals pointer event loop (#3324) -> 100ms setTimeout delay
+- Traffic light buttons flicker due to timeout race (#3488, #3129)
+- Android tool buttons unresponsive due to premature re-selection (#3225)
+
+**Fix Strategy:** Add small delays before native menu calls. Check event state machine consistency. Remove premature re-triggers on Android.
+
+### 9. foliate-js Rendering Issues
+**Pattern:** Bugs in the lower-level EPUB renderer (paginator.js, epub.js).
+**Examples:**
+- Image size not constrained in double-page mode (#3432)
+- Background not shown in scrolled mode (#3344)
+- Section content cached incorrectly after mode switch (#3242, #3206)
+- Swipe sensitivity too low for non-animated paging (#3310)
+
+**Fix Strategy:** Check both `columnize()` and `scrolled()` code paths in paginator.js. Verify CSS variables (`--available-width`, `--available-height`) are computed correctly. Test in both paginated and scrolled modes.
+
+### 10. Progress/Navigation Calculation Errors
+**Pattern:** Page counts, progress percentages, or position tracking are wrong.
+**Examples:**
+- Progress shows 99.9% at last page (#3383) -> boundary condition
+- Pages left shows estimated instead of physical count (#3213, #3200)
+- FB2 subsection progress wrong (#3136) -> nested structure not handled
+- TOC auto-scrolls on expand (#3124) -> scroll-into-view triggered too broadly
+
+**Fix Strategy:** Use physical `view.renderer.page`/`view.renderer.pages` instead of estimated section metadata. Check boundary conditions (0-indexed vs 1-indexed, inclusive vs exclusive).
+
+### 11. Multiview Paginator Side Effects
+**Pattern:** The multiview paginator (e925e9d+) loads adjacent sections in background. Events from these loads can interfere with user interactions on the primary section.
+**Examples:**
+- `load` event from adjacent section triggers `docLoadHandler` which re-adds ALL annotations, overwriting drag edits
+- Multiple overlayers with duplicate SVG `<clipPath>` IDs cause `url(#id)` to resolve to wrong element
+- `MagnifierLoupe` destroying/recreating body clone on every drag tick triggers ResizeObserver → expand → redraw
+
+**Fix Strategy:** Scope event handlers to the loaded section's index. Use unique IDs for SVG elements across overlayer instances. Minimize iframe DOM mutations during drag operations.
+
+## Debugging Workflow
+
+1. **Identify the category** from the issue description
+2. **Check `style.ts`** first for any CSS-related visual bugs
+3. **Check foliate-js** for rendering/layout bugs
+4. **Check platform-specific code** for mobile/desktop differences
+5. **Write a failing test** before implementing the fix
+6. **Test in both paginated and scrolled modes** for layout changes
+7. **Test on multiple platforms** for any UI change
+8. **Run `pnpm build-check`** before submitting

+# CSS & Style Fixes Reference
+
+## The `style.ts` Pipeline (`src/utils/style.ts`)
+
+This is the most bug-prone file in the codebase (14+ fixes). It handles all EPUB CSS transformations.
+
+### Key Functions
+
+#### `getLayoutStyles()`
+- Always-active styles applied to every EPUB section
+- Controls: line-height, hyphens, image sizing, table display
+- Rules here should NOT be conditional on user settings
+- Common mistake: putting color-related rules here instead of `getColorStyles()`
+
+#### `getColorStyles()`
+- Conditionally applied when user enables "Override Book Color"
+- Controls: foreground/background colors, mix-blend modes, image backgrounds
+- Gate rules on `overrideColor` flag
+
+#### `transformStylesheet()`
+- Regex-based rewriting of EPUB CSS at load time
+- Runs on every stylesheet loaded from the EPUB
+- Used to neutralize problematic EPUB CSS declarations
+
+#### `applyTableStyle()`
+- Post-render function that scales tables to fit available width
+- Uses `getComputedStyle()` (not inline `style.width`) to read actual width
+- Has two scaling paths: column-width-based and parent-container-based
+
+### Fix History by Issue
+
+| Issue | Problem | Fix in style.ts |
+|-------|---------|-----------------|
+| #3494 | Line spacing not on `<li>` | Added `li` CSS rule for `line-height` and `hyphens` |
+| #3448 | Calibre colors persist | Moved `.calibre` unset to `getColorStyles()`, added `background-color: unset` |
+| #3441 | Body padding/margin | Added `padding: unset; margin: unset` to body in `getLayoutStyles()` |
+| #3316 | Image bg unconditional | Made `background-color` rule conditional on `overrideColor` |
+| #3377 | Image bg override | Same pattern as #3316, only override when `overrideColor` is true |
+| #3334 | Generic font-family | `transformStylesheet()` replaces `font-family: serif/sans-serif` with `unset` on body |
+| #3370 | user-select: none | `transformStylesheet()` replaces all `user-select: none` with `unset` |
+| #3284 | Table scaling | Added fallback when `totalTableWidth` is 0 but parent has width |
+| #3351 | Table display broken | Added `display: table !important` to table rule |
+| #3274 | Image dimensions | Changed selectors to `:where(:not([width]))` and `:where(:not([height]))` |
+| #3205 | Table width reading | Changed from `style.width` to `getComputedStyle().width`, fixed CSS var unit |
+| #3112 | Mix-blend on all images | Narrowed selector to `.has-text-siblings` class |
+| #3086 | Mix-blend on hr | Narrowed selector to `hr.background-img` |
+| #3012 | Vertical alignment | Fixed available dimensions (subtract insets), replaced `100vw/vh` with CSS vars |
+
+### Common Patterns
+
+1. **Adding new element rules:** Copy the pattern from `p` rules (e.g., adding `li` for #3494)
+2. **EPUB CSS neutralization:** Add regex in `transformStylesheet()` to replace problematic declarations
+3. **Conditional overrides:** Use `overrideColor`/`overrideLayout` flags to gate rules
+4. **Selector narrowing:** Use class qualifiers or attribute pseudo-selectors to avoid over-matching
+5. **Table fixes:** Always use `getComputedStyle()`, not inline style. Check both width paths.
+
+### CSS Variables from foliate-js
+
+- `--available-width` - Usable content width (set by paginator.js)
+- `--available-height` - Usable content height
+- `--full-width` - Full viewport width (numeric, multiply by 1px)
+- `--full-height` - Full viewport height (numeric, multiply by 1px)
+- `--overlayer-highlight-opacity` - Highlight transparency (default 0.3)
+
+### foliate-js Rendering (`packages/foliate-js/paginator.js`)
+
+Key functions:
+- `columnize()` - Paginated layout path
+- `scrolled()` - Scrolled layout path
+- `setImageSize()` - Constrains image dimensions to available space
+- `#replaceBackground()` - Transfers EPUB backgrounds to paginator layer
+- `snap()` - Swipe gesture detection for page turning
+
+Common issue: A fix applied to `columnize()` but not `scrolled()` (or vice versa). Always check both paths.

+name: D-pad Navigation Design
+description: Android TV / Bluetooth remote D-pad navigation architecture, key files, and pitfalls encountered during implementation
+type: project
+---
+
+## D-pad Navigation Architecture
+
+D-pad support enables Bluetooth remote controller navigation on Android TV (and keyboard arrow navigation on desktop).
+
+### Key Files
+
+- `src/app/reader/hooks/useSpatialNavigation.ts` — Reader toolbar D-pad navigation. Left/Right navigates between buttons, Up/Down moves between header↔footer. Auto-focuses first button on show. Uses focus-probe technique for visibility detection.
+- `src/app/library/hooks/useSpatialNavigation.ts` — Library grid D-pad navigation. Arrow keys move between BookshelfItem elements. ArrowDown from outside bookshelf (e.g. header) enters the grid via window-level listener.
+- `src/helpers/shortcuts.ts` — `onToggleToolbar` (Enter key) toggles reader toolbar visibility.
+- `src/app/reader/hooks/useBookShortcuts.ts` — `toggleToolbar` handler shows/hides header+footer bars. Skips when a `<button>` is focused (lets native click fire).
+- `src/__tests__/hooks/useSpatialNavigation.test.tsx` — Unit tests for reader toolbar navigation.
+
+### Design Decisions
+
+- **No third-party library**: Tried `@noriginmedia/norigin-spatial-navigation` but it failed due to init timing issues (React child effects run before parent effects) and conflicts with the existing `useShortcuts` system. Custom solution is simpler and more reliable.
+- **Two `useSpatialNavigation` hooks**: Same name in different directories — library version handles grid navigation, reader version handles toolbar button navigation. Different navigation patterns but same concept.
+- **Platform-agnostic hooks**: Both `useSpatialNavigation` hooks work on all platforms, not just Android.
+- **Focus-probe for visibility**: `offsetParent` is unreliable for detecting visible buttons (returns null inside `position: fixed` containers on mobile). Instead, try `btn.focus()` and check if `document.activeElement === btn` — this correctly handles all hiding methods (display:none, visibility:hidden, fixed positioning).
+
+### Pitfalls
+
+1. **WebView spatial navigation conflict**: Android WebView has built-in spatial navigation that intercepts D-pad arrow keys and moves DOM focus between `tabIndex>=0` elements. Added `tabIndex={-1}` to non-interactive overlay elements (HeaderBar trigger, ProgressBar, FooterBar trigger, SectionInfo) to prevent focus theft.
+
+2. **`eventDispatcher.dispatchSync` short-circuits**: When multiple handlers are registered for `native-key-down`, the first handler returning `true` stops propagation. The FooterBar's Back handler fires before the Reader's. Both must independently call `blur()` — can't rely on the Reader's handler running.
+
+3. **Must blur on toolbar dismiss**: When Back/Escape dismisses the toolbar, the focused button must be blurred. Otherwise `document.activeElement` remains a hidden button, and `toggleToolbar` skips Enter when `activeElement.tagName === 'BUTTON'`. Blur is called in FooterBar's handleKeyDown (for Back and Escape) and in Reader's handleKeyDown.
+
+4. **Arrow key trapping must use `stopPropagation`**: Without it, arrow keys bubble to `window` where `useShortcuts` handles them as page turns. The toolbar keydown handler on the container div calls `e.stopPropagation()` + `e.preventDefault()` to prevent this.
+
+5. **Library grid needs window-level listener**: The bookshelf container keydown handler only fires when focus is inside it. A separate `window` keydown listener handles ArrowDown from the header into the grid (when focus is outside the container).
+
+6. **Auto-focus race on toolbar show**: Both header and footer bars auto-focus their first button when `isVisible` becomes true simultaneously. The last effect to run wins. This is acceptable — user can navigate between them with Up/Down.
+
+7. **`offsetParent` null in fixed containers**: On mobile, `.footer-bar` uses `position: fixed`. All child buttons have `offsetParent === null`, making `offsetParent`-based visibility checks useless. The focus-probe approach (try focus, check activeElement) is the reliable alternative.

+
+When upgrading gstack, always run the upgrade from the current project's `.claude/skills/gstack` directory (local-git install), not from a global install path.
+
+**Why:** The project uses a local-git gstack install at `apps/readest-app/.claude/skills/gstack`. Previous mistakes upgraded a global copy while the project's local copy stayed outdated.
+
+**How to apply:** When `/gstack-upgrade` is invoked, ensure the `cd` and `git reset --hard origin/main && ./setup` happen inside the project's `.claude/skills/gstack` directory.

+# Layout & UI Fixes Reference
+
+## Safe Area Insets
+
+### Architecture
+- Native plugins push inset values: iOS (`NativeBridgePlugin.swift`), Android (`NativeBridgePlugin.kt`)
+- `useSafeAreaInsets` hook (`src/hooks/useSafeAreaInsets.ts`) reads and caches values
+- Components use `gridInsets` for positioning relative to safe areas
+- CSS: `env(safe-area-inset-top/bottom/left/right)` for CSS-level insets
+
+### Common Issues
+- **Stale insets after system UI change** (#3469): Call `onUpdateInsets()` after `setSystemUIVisibility()`
+- **iPad sidebar insets wrong** (#3395): Different inset handling needed for sidebar vs main view
+- **Android nav bar overlap** (#3466): Use `calc(env(safe-area-inset-bottom) + 16px)` for Android bottom padding
+- **Zoom controls behind status bar** (#3426): Pass `gridInsets` through component chain, use `Math.max(gridInsets.top, statusBarHeight)`
+
+### Rules (see also `docs/safe-area-insets.md`)
+- Always pass `gridInsets` to overlay/floating components near screen edges
+- On Android, account for system navigation bar with `env(safe-area-inset-bottom)`
+- After toggling system UI visibility, force-refresh insets via `onUpdateInsets()`
+
+## Z-Index Hierarchy
+- Navigation buttons: `z-10` (when visible)
+- Annotation nav bar: `z-10` (reduced from z-30 in #3386)
+- TTS control button: ensure above page nav buttons
+- Floating overlays: check against `gridInsets` positioning
+
+## macOS Traffic Lights
+- Managed by `trafficLightStore.ts` and `HeaderBar.tsx`
+- **Fullscreen check required** (#3129): `await currentWindow.isFullscreen()` before hiding
+- **Timeout for visibility toggle** (#3488): Use 100ms delay to prevent flickering
+- **Sidebar interaction** (#3488): Check `getIsSideBarVisible()` before hiding traffic lights
+- Never hide traffic lights when sidebar is open
+
+## Touch/Input Issues
+- **Slider hit area on iOS** (#3382): Use min-h-12, strip browser appearance with CSS
+- **Context menu on macOS** (#3324): 100ms delay before `onContextMenu()` to let pointer events complete
+- **Swipe sensitivity** (#3310): Use average velocity (distance/time) instead of instantaneous velocity for non-animated paging
+- **Touchpad natural scrolling** (#3127): Respect system natural scrolling setting in `usePagination.ts`
+
+## Dialog/Menu Layout
+- **Dialog header** (#3352): Use `px-2 sm:pe-3 sm:ps-2` padding to align with border radius
+- **Settings alignment** (#3151): Use `Menu` component instead of raw `div` for consistent styling
+- **Dropdown for screen readers** (#3035): Use `DropdownContext` with overlay dismiss, not blur-based closing
+
+## Component-Specific Fixes
+
+### HeaderBar.tsx
+- Traffic light visibility management
+- Sidebar toggle persistent position (#3193)
+- Library button placement
+
+### PageNavigationButtons.tsx
+- z-10 when visible (#3201)
+- Always shown for screen readers (#3036)
+- Toggle via `showPageNavButtons` setting
+
+### ProgressInfo.tsx
+- Use physical `page`/`pages` from renderer, not estimated values (#3213, #3200)
+- CSS classes: `time-left-label`, `pages-left-label`, `progress-info-label` (#3343)
+
+### ReadingRuler.tsx
+- Remove `containerStyle` from overlay so dimmed area covers full screen (#3304)
+
+### NavigationBar.tsx
+- Handle `gridInsets` internally, not via pre-computed `navPadding` (#3466)
+
+### ContentNavBar.tsx (annotation search results)
+- Floating buttons with drop shadow, not full-width bar (#3386)
+- z-10 z-index

+# Platform Compatibility Fixes Reference
+
+## Android
+
+### WebView API Issues
+- **`navigator.getGamepads()`** returns null on older WebView (#3245): Always null-check before `.some()`
+- **`CompressionStream`** unavailable on some Android WebView versions (#3255): Add fallback zip compression path
+- **Annotation tools unresponsive** (#3225): Don't call `makeSelection()` immediately on pointer-up; let popup flow complete naturally
+- **Safe inset updates** (#3469): Call `onUpdateInsets()` after `setSystemUIVisibility()`
+- **Navigation bar overlap** (#3466): Use `calc(env(safe-area-inset-bottom) + 16px)` for bottom padding
+
+### General Android Rules
+- Test with older WebView versions (97+)
+- Always check API availability before calling Web APIs
+- Touch event handling differs from iOS - avoid premature re-selection
+
+## iOS
+
+### Common Issues
+- **Slider touch dead zones** (#3382): Strip native appearance, use larger hit areas (min-h-12)
+- **Safe area insets stale** (#3395): Native Swift plugin must push updated insets
+- **Section content caching** (#3242, #3206): Don't cache section content in foliate-js when updating subitems; cached content retains stale styles after mode switch
+- **CompressionStream** (#3255): Also broken on iOS 15.x; zip.js has its own native API disable
+- **zip.js native API** (#3170): Disable native `CompressionStream`/`DecompressionStream` on iOS 15.x
+
+### iOS-Specific Code
+- `src-tauri/plugins/tauri-plugin-native-bridge/ios/Sources/NativeBridgePlugin.swift`
+- Slider CSS: `-webkit-appearance: none; appearance: none` in globals.css
+- `useSafeAreaInsets.ts` hook
+
+## macOS
+
+### Traffic Lights (Window Controls)
+- Check `isFullscreen()` before hiding (#3129)
+- Use timeouts (100ms) for visibility transitions (#3488)
+- Don't hide when sidebar is open (#3488)
+
+### Input Issues
+- **Context menu steals event loop** (#3324): 100ms setTimeout before calling menu.popup()
+- **Touchpad natural scrolling** (#3127): Respect system setting in `usePagination.ts`
+- **Two-finger swipe** (#3127): Support trackpad two-finger swipe for pagination
+
+### macOS-Specific Code
+- `src-tauri/src/macos/` - Platform-specific Rust code
+- `src/store/trafficLightStore.ts`
+- `src/hooks/useTrafficLight.ts`
+
+## Linux
+
+### WebKitGTK Issues
+- **View Transitions API unsupported** (#3417): Feature-detect `document.startViewTransition` before calling
+- Use `useAppRouter.ts` to avoid transitions on Linux
+
+## E-ink Devices
+
+### Legibility Issues
+- **Low contrast colors** (#3258): Use `not-eink:` Tailwind variant prefix for colors/opacity
+- **Links invisible** (#3258): Don't apply `text-primary` (blue) on e-ink; use default text color
+- **Opacity too low** (#3258): Don't apply `opacity-60`/`opacity-75` on e-ink devices
+- **Highlight visibility** (#3299): Use foreground color for highlights in dark mode e-ink
+
+### E-ink CSS Pattern
+```
+// Instead of:
+className="text-primary opacity-60"
+// Use:
+className="not-eink:text-primary not-eink:opacity-60"
+```
+
+## Docker/Self-Hosting
+- **Missing submodules** (#3233): Run `git submodule update --init --recursive` before build
+- Simplecc WASM module must be initialized
+
+## OPDS
+- **Non-ASCII credentials** (#3436): Use `TextEncoder` + manual Base64 instead of `btoa()`
+- **Author parsing** (#3120): Handle varied metadata structures in OPDS 2.0 feeds
+- **Responsive layout** (#3418): Ensure catalog and download button layout works on small screens
+
+## Cross-Platform Testing Checklist
+1. Android (old WebView + current)
+2. iOS (15.x + current)
+3. macOS (traffic lights, trackpad)
+4. Linux (WebKitGTK)
+5. E-ink devices (contrast, colors)
+6. Web (CloudFlare Workers deployment)

+# TTS (Text-to-Speech) Fixes Reference
+
+## Architecture
+
+### Key Components
+- `TTSController` (`src/services/tts/TTSController.ts`) - Core state machine
+- `EdgeTTSClient` (`src/services/tts/EdgeTTSClient.ts`) - Edge TTS provider
+- `useTTSControl` hook (`src/app/reader/hooks/useTTSControl.ts`) - React integration
+- `useTTSMediaSession` hook (`src/app/reader/hooks/useTTSMediaSession.ts`) - Media controls
+
+### Section-Aware TTS Model
+TTS tracks its own section independently from the view via `#ttsSectionIndex`:
+- `#initTTSForSection()` - Creates TTS document for a section without changing the view
+- `#initTTSForNextSection()` / `#initTTSForPrevSection()` - Navigate TTS across sections
+- `#getHighlighter()` - Only returns highlighter if view section matches TTS section
+- `onSectionChange` callback - Notifies UI when TTS crosses section boundary
+- Highlights use CFI strings (not raw Range objects) for cross-section compatibility
+
+### State Management Pitfalls
+1. **`#ttsSectionIndex` must match view section for highlights to work**
+   - If `-1`, all highlight calls are suppressed
+   - `shutdown()` sets it to `-1` but must also null out `this.view.tts`
+
+2. **Guards/Refs that block re-entry:**
+   - The old `ttsOnRef` guard blocked TTS restart from annotations (removed in #3292)
+   - `view.tts` reference surviving shutdown blocked re-initialization (#3400)
+
+3. **Timeouts that fire after pause:**
+   - Edge TTS had a safety timeout that advanced sentences even when paused (#3244)
+   - Solution: removed the entire `ontimeupdate` safety timeout mechanism
+
+## Fix History
+
+| Issue | Problem | Root Cause | Fix |
+|-------|---------|------------|-----|
+| #3100 | TTS scrolls too far | TTS coupled to view section | Added `#ttsSectionIndex`, "Back to TTS Location" button |
+| #3198 | TTS doesn't follow to next section | No `onSectionChange` callback | Added section change notification, extracted hooks |
+| #3244 | Paused TTS advances | Safety timeout fires after pause | Removed `ontimeupdate` timeout mechanism |
+| #3291 | TTS fails without lang attribute | Invalid SSML from missing lang | Set lang/xml:lang on html element from `ttsLang` |
+| #3292 | Can't restart TTS from annotation | `ttsOnRef` blocks re-entry | Removed the guard ref entirely |
+| #3400 | TTS highlight stops after restart | `view.tts` not nulled on shutdown | Added `this.view.tts = null` in `shutdown()` |
+
+## Debugging TTS Issues
+
+1. **TTS doesn't start:** Check `#initTTSForSection()` - does `view.tts.doc === doc` shortcut early?
+2. **No highlights:** Check `#ttsSectionIndex` matches view's section index
+3. **Advances when paused:** Look for setTimeout/timer callbacks that bypass pause state
+4. **Can't restart:** Check for refs/guards that prevent re-entry into speak handlers
+5. **Fails on some chapters:** Check if chapter has lang attribute and XHTML namespace
+6. **SSML errors:** Check `src/utils/ssml.ts` for proper namespace/lang handling

+## Project Overview
+
+Readest is a cross-platform ebook reader built as a **Next.js 16 + Tauri v2** hybrid app. It's part of a pnpm monorepo at `/apps/readest-app/`. The app runs on web (CloudFlare Workers), desktop (macOS/Windows/Linux via Tauri), and mobile (iOS/Android via Tauri).
+
+## Common Commands
+
+```bash
+# Development
+pnpm dev-web               # Web-only dev server (no Rust compilation needed)
+pnpm tauri dev             # Desktop dev with Tauri (compiles Rust backend)
+
+# Building
+pnpm build                 # Build Next.js for Tauri
+pnpm build-web             # Build Next.js for web deployment
+
+# Testing (see [docs/testing.md](docs/testing.md) for full details)
+pnpm test                  # Unit tests (vitest + jsdom)
+pnpm test -- src/__tests__/utils/misc.test.ts  # Run a single test file
+pnpm test -- --watch       # Watch mode

+### Rust Backend (`src-tauri/`)
+
+Platform-specific code lives in `src-tauri/src/{macos,windows,android,ios}/`. Custom Tauri plugins are in `src-tauri/plugins/`.
+
+## Project Rules
+
+Rules are in `.claude/rules/`: test-first, typescript, verification.
+
+### i18n
+
+See [docs/i18n.md](docs/i18n.md) for the key-as-content translation approach, `stubTranslation` usage in non-React modules, and extraction workflow.
+
+### Safe Area Insets
+
+See [docs/safe-area-insets.md](docs/safe-area-insets.md) for rules on handling top/bottom insets for UI elements near screen edges.
+
+## Web Browsing & QA (gstack)
+
+For all web browsing, QA testing, and site interaction, use the `/browse` skill from gstack. **Never use `mcp__claude-in-chrome__*` tools directly.**
+
+Available gstack skills:
+
+- `/plan-ceo-review` — CEO/founder-mode plan review
+- `/plan-eng-review` — Eng manager-mode plan review
+- `/plan-design-review` — Designer's eye review of a live site
+- `/design-consultation` — Design system consultation
+- `/review` — Pre-landing PR review
+- `/ship` — Ship workflow (merge, test, review, bump, PR)
+- `/browse` — Fast headless browser for QA and site interaction
+- `/qa` — QA test and fix bugs
+- `/qa-only` — QA report only (no fixes)
+- `/qa-design-review` — Designer's eye QA with fixes
+- `/setup-browser-cookies` — Import cookies for authenticated testing
+- `/retro` — Weekly engineering retrospective
+- `/document-release` — Post-ship documentation update
+
+If gstack skills aren't working, run `cd .claude/skills/gstack && ./setup` to build the binary and register skills.

+## i18n Guide
+
+Readest uses a **key-as-content** approach — English strings are the translation keys. The English locale (`en/translation.json`) is empty because keys serve as content. Other locales contain actual translations.
+
+### In React Components
+
+```tsx
+import { useTranslation } from '@/hooks/useTranslation';
+
+const _ = useTranslation();
+_('Progress synced');
+```
+
+### In Non-React Modules
+
+Two-step process:
+
+**1. Declaration** — Use `stubTranslation` to mark strings for scanner extraction (returns key as-is, does NOT translate):
+
+```ts
+import { stubTranslation as _ } from '@/utils/misc';
+
+// These calls only register keys for extraction
+_('Reveal in Finder');
+_('Reveal in Explorer');
+```
+
+**2. Usage** — In the React component that consumes the value, apply the real `_()` from `useTranslation`:
+
+```tsx
+const _ = useTranslation();
+const label = _(getRevealLabel()); // translates at runtime
+```
+
+### Extraction & Translation
+
+```bash
+pnpm i18n:extract    # Scans codebase, adds new keys with __STRING_NOT_TRANSLATED__
+```
+
+- Translation files: `public/locales/<locale>/translation.json`
+- Only `_('KEY')` and `_('KEY', options)` patterns are recognized by i18next-scanner
+
+### Rules
+
+- `stubTranslation` is for extraction only — always apply `_()` from `useTranslation` in the component for runtime translation.
+- Fallback: when no translation exists, the English key itself is displayed.
+- Error messages: register keys with `stubTranslation` in utility modules (e.g. `src/services/errors.ts`), return the English key from helpers, wrap with `_()` in the component.

+## Safe Area Insets
+
+The app runs on devices with notches, status bars, and rounded corners (iOS, Android). UI elements near screen edges must account for safe area insets to avoid being obscured.
+
+### Key Concepts
+
+- **`gridInsets: Insets`** — Per-view insets derived from view settings (header/footer visibility, margins). Calculated by `getViewInsets()` in `src/utils/insets.ts`. Passed as a prop from `BooksGrid` → child components.
+- **`statusBarHeight: number`** — OS status bar height (default 24px). Stored in `themeStore`.
+- **`systemUIVisible: boolean`** — Whether the system UI (status bar, navigation bar) is currently shown. Stored in `themeStore`.
+- **`appService?.hasSafeAreaInset`** — Whether the platform requires safe area handling (mobile devices).
+
+### Top Inset Rules
+
+For UI elements anchored to the **top** of the screen (headers, close buttons, overlays):
+
+```tsx
+// When system UI is visible, use the larger of gridInsets.top and statusBarHeight
+// When system UI is hidden, use gridInsets.top alone
+style={{
+  marginTop: systemUIVisible
+    ? `${Math.max(gridInsets.top, statusBarHeight)}px`
+    : `${gridInsets.top}px`,
+}}
+```
+
+For containers that need safe area padding at the top:
+
+```tsx
+style={{
+  paddingTop: appService?.hasSafeAreaInset ? `${gridInsets.top}px` : '0px',
+}}
+```
+
+### Bottom Inset Rules
+
+For UI elements anchored to the **bottom** of the screen (footer bars, controls, progress indicators), use `gridInsets.bottom * 0.33` as padding — a fraction of the full inset since bottom bars don't need as much clearance as the home indicator area:
+
+```tsx
+style={{
+  paddingBottom: appService?.hasSafeAreaInset ? `${gridInsets.bottom * 0.33}px` : 0,
+}}
+```
+
+### Passing `gridInsets`
+
+When creating overlay components (image viewers, table viewers, zoom controls, etc.), always pass `gridInsets` as a prop so they can position their controls correctly:
+
+```tsx
+<ImageViewer gridInsets={gridInsets} ... />
+<TableViewer gridInsets={gridInsets} ... />
+<ZoomControls gridInsets={gridInsets} ... />
+```

+# Testing
+
+Readest uses three test tiers, all powered by [Vitest](https://vitest.dev/).
+
+## Unit Tests (`pnpm test`)
+
+Runs tests in a **jsdom** environment. No browser or Tauri runtime required.
+
+```bash
+pnpm test                                       # Run all unit tests
+pnpm test -- src/__tests__/utils/misc.test.ts   # Run a single file
+pnpm test -- --watch                            # Watch mode
+```
+
+- **Config:** `vitest.config.mts`
+- **Pattern:** `src/**/*.test.ts` (excludes `*.browser.test.ts` and `*.tauri.test.ts`)
+- **Environment:** jsdom
+- **Use for:** Pure logic, utilities, services that don't need real browser APIs or Tauri IPC.
+
+## Browser Tests (`pnpm test:browser`)
+
+Runs tests in a **real Chromium** browser via Playwright. Required for code that depends on Web Workers, SharedArrayBuffer, OPFS, or other browser-only APIs.
+
+```bash
+pnpm test:browser
+```
+
+- **Config:** `vitest.browser.config.mts`
+- **Pattern:** `src/**/*.browser.test.ts`
+- **Browser:** Chromium (headless, via `@vitest/browser-playwright`)
+- **Use for:** WASM modules (e.g. `@tursodatabase/database-wasm`), Web Worker integration, browser-specific storage APIs.
+
+## Tauri Integration Tests (`pnpm test:tauri`)
+
+Runs Vitest tests **inside the Tauri WebView**, with access to Tauri IPC and native plugin commands. Tests execute in the actual app environment.
+
+### Step 1: Start the Tauri App
+
+In one terminal, start the app with the `webdriver` feature enabled:
+
+```bash
+pnpm tauri:dev:test     # Dev mode (uses tauri dev server, faster iteration)
+pnpm tauri:build:test   # Debug release build (closer to production)
+```
+
+These commands compile the Rust backend with `--features webdriver`, which:
+
+- Includes `tauri-plugin-webdriver` (embeds a W3C WebDriver server on port 4445)
+- Adds a runtime capability granting plugin permissions to remote URLs (`http://127.0.0.1:*`), so Vitest's browser-mode iframe can call Tauri IPC
+
+Keep this running while you run tests.
+
+### Step 2: Run Tests
+
+In another terminal:
+
+```bash
+pnpm test:tauri
+```
+
+Vitest connects directly to the embedded WebDriver server (port 4445) in the running Tauri app and executes tests inside its WebView.
+
+- **Config:** `vitest.tauri.config.mts`
+- **Pattern:** `src/**/*.tauri.test.ts`
+- **Browser provider:** `@vitest/browser-webdriverio` (connects to port 4445)
+- **Use for:** Tauri plugin commands (turso, native-tts, etc.), native filesystem, Tauri IPC.
+
+### Writing Tauri Tests
+
+Tests access Tauri IPC via a shared helper:
+
+```typescript
+import { invoke } from '../tauri/tauri-invoke';
+
+it('calls a plugin command', async () => {
+  const result = await invoke('plugin:turso|load', { options: { path: 'sqlite::memory:' } });
+  expect(result).toBeDefined();
+});
+```
+
+The `invoke()` helper accesses `window.top.__TAURI_INTERNALS__` (Vitest runs in an iframe, Tauri injects IPC into the main frame).
+
+**Limitations:** Only custom invoke commands and plugin commands listed in the webdriver capability work. Standard Tauri JS APIs (e.g. `@tauri-apps/api`) that rely on `URL: local` may not work from the Vitest iframe.
+
+## E2E Tests (WDIO)
+
+Full end-to-end tests using WebDriverIO, for UI-level testing against the running Tauri app. Same two-step workflow as Tauri integration tests.
+
+```bash
+# Terminal 1: start the app (same as for Tauri integration tests)
+pnpm tauri:dev:test
+
+# Terminal 2: run E2E tests
+pnpm test:e2e
+```
+
+- **Config:** `wdio.conf.ts`
+- **Pattern:** `e2e/**/*.e2e.ts`
+- **Framework:** Mocha (via `@wdio/mocha-framework`)
+- **Connects to:** port 4445 (embedded WebDriver server)
+- **Use for:** UI interaction tests, window management, navigation flows.
+
+## Test File Naming
+
+| Suffix              | Runner              | Environment           |
+| ------------------- | ------------------- | --------------------- |
+| `*.test.ts`         | `pnpm test`         | jsdom                 |
+| `*.browser.test.ts` | `pnpm test:browser` | Chromium (Playwright) |
+| `*.tauri.test.ts`   | `pnpm test:tauri`   | Tauri WebView         |
+| `*.e2e.ts`          | `pnpm test:e2e`     | Tauri app (WDIO)      |

+# Windows Thumbnail Provider for Readest
+
+This crate provides Windows Explorer thumbnail support for eBook files when Readest is set as the default application.
+
+## Features
+
+- **Automatic Cover Extraction**: Extracts cover images from EPUB, MOBI, AZW, AZW3, FB2, CBZ, CBR files
+- **Readest Branding**: Adds a small Readest icon overlay at the bottom-right corner
+- **Smart Caching**: Caches generated thumbnails for faster subsequent loads
+- **File Association Aware**: Only shows thumbnails when Readest is the default app for the file type
+- **COM Integration**: Full Windows Shell extension implementation via `IThumbnailProvider`
+
+## Supported Formats
+
+| Format     | Extension               | Cover Source                 |
+| ---------- | ----------------------- | ---------------------------- |
+| EPUB       | `.epub`                 | OPF manifest cover reference |
+| MOBI/AZW   | `.mobi`, `.azw`, `.prc` | EXTH cover offset            |
+| AZW3/KF8   | `.azw3`, `.kf8`         | KF8 format cover             |
+| FB2        | `.fb2`                  | `<binary>` coverpage element |
+| Comic Book | `.cbz`, `.cbr`          | First image in archive       |
+| Plain Text | `.txt`                  | Generated placeholder        |
+
+## Building
+
+### Library Only
+
+```bash
+cargo build --release
+```
+
+### COM DLL (for Windows Explorer integration)
+
+```bash
+cargo build --release --features com
+```
+
+### CLI Tool
+
+```bash
+cargo build --release --features cli
+```
+
+## Installation
+
+The thumbnail provider DLL is automatically registered when Readest is installed via the NSIS installer.
+
+### Manual Registration (for development)
+
+```powershell
+# Register the DLL
+regsvr32 /s target\release\windows_thumbnail.dll
+
+# Unregister the DLL
+regsvr32 /s /u target\release\windows_thumbnail.dll
+
+# Refresh Explorer to see changes
+ie4uinit.exe -show
+```
+
+After registration, you may need to restart Windows Explorer or log out/in for changes to take effect.
+
+## Usage (Development / Manual testing)
+
+For local development and testing, build the Windows DLL (or the library) from the Readest Tauri app folder and register it manually. The legacy CLI test harness used to live in the separate `packages/tauri` workspace, but the thumbnail handler implementation now lives inside Readest's Tauri app.
+
+Build the DLL (for Windows explorer integration):
+
+```powershell
+cd apps/readest-app/src-tauri
+cargo build --release --manifest-path Cargo.toml --features com
+```
+
+The standalone CLI test harness is no longer distributed with the app. To test the thumbnail provider locally, build and register the DLL as shown above and use a small test harness that imports `readestlib`'s thumbnail code or use Explorer after registering the handler.
+
+Manual registration for development (register the generated DLL):
+
+```powershell
+# Register the DLL
+regsvr32 /s target\release\windows_thumbnail.dll
+
+# Unregister the DLL
+regsvr32 /s /u target\release\windows_thumbnail.dll
+
+# Refresh Explorer to see changes
+ie4uinit.exe -show
+```
+
+This generates a thumbnail with the Readest overlay at the specified size.

+## COM Details
+
+- **CLSID**: `{A1B2C3D4-E5F6-7890-ABCD-EF1234567890}`
+- **Shell Thumbnail Handler GUID**: `{e357fccd-a995-4576-b01f-234630154e96}`
+- **Threading Model**: Apartment
+
+## How It Works
+
+1. When Windows Explorer needs a thumbnail, it queries the registered shell extension
+2. The COM DLL implements `IInitializeWithItem` to receive the file path
+3. It checks if Readest.exe is the default application for that file type using `AssocQueryStringW`
+4. If Readest is the default, it extracts the cover and generates the thumbnail
+5. If Readest is NOT the default, it returns `S_FALSE` to let Windows use other handlers
+
+This ensures thumbnails only appear for files the user has associated with Readest.
