Huang Xin 772bb73b46 ui/ux: codify design system and migrate settings to shared primitives (#4116)
* ui/ux: codify design system and migrate settings to shared primitives

Document Readest's design language in DESIGN.md (Adwaita-aligned, e-ink-first,
RTL-correct) and migrate every settings panel onto a small set of primitives
(BoxedList, SettingsRow, SettingsSwitchRow, SettingsSelect, SettingsInput,
NavigationRow, Tips, SubPageHeader). AGENTS.md links to DESIGN.md so contributors
land there before inventing new chassis classes.

Replace the standalone KOReader/Readwise/Hardcover Config dialogs with a single
Integrations panel (Reading Sync + Content Sources sub-pages). The reader's
BookMenu now hides each provider until it's configured, and Hardcover's per-book
"Enable for This Book" toggle is dropped — there's no auto-sync to gate, so the
flag was just extra clicks.

Refresh highlight colors (two-trigger swatch + label, translatable default
names), background texture / theme color selectors (border-current keeps
selection legible on any backdrop), CustomFonts/CustomDictionaries (quiet
list-extension style + shared Tips primitive), the OPDS catalog manager
(debounced auto-download, right-aligned Browse), Set PIN, and the KOSync
conflict resolver. Translate the ~30 new strings across all 33 locales.

* ui/ux: responsive typography, OPDS card polish, deep-link return paths

Restore the .settings-content responsive cascade (14px desktop / 16px
mobile) the legacy panels relied on by dropping hardcoded `text-sm`/`text-xs`
from the new primitives. Secondary text moves to em-relative `text-[0.85em]`
so it scales with the parent. Form controls (`<input>`, `<select>`) re-apply
the cascade explicitly via the `settings-content` class since browsers don't
inherit font-size onto form elements.

Extract `<SectionTitle>` primitive (caseless-language aware via
`isCaselessUILang`/`isCaselessLang`) and route every uppercase tag-style
header through it: BoxedList groups, Reading Sync, Content Sources, Theme
Color, Background Image, integration form labels, KOSyncResolver device
labels, and the OPDS My Catalogs / Popular Catalogs sections. CJK / Arabic
/ Hebrew / Indic / Thai / Tibetan locales bump to `1em` since `uppercase`
is a no-op on those scripts.

Redesign the OPDS My Catalogs cards: whole card becomes the browse trigger
(role='button'), edit/delete collapse into a 3-dot dropdown menu, and the
sync-status moves to a sub-line under Auto-download so the card height stays
constant whether the toggle is on/off or sync data has arrived.

Plumb a `from=settings-integrations` URL marker through the OPDS browser so
both manual close and auto-close-on-failure (preserved as `router.back()`
for transient failures, paired with a new `stashOPDSReturnTarget` helper)
return the user to Settings -> Integrations -> OPDS Catalogs sub-page
rather than the dialog's top level. Backed by new `requestedSubPage`
deep-link store field.

Skip the OPDS catalog passphrase prompt when credentials sync is disabled
-- `replicaPublish` already drops encrypted fields at the wire, so prompting
was both pointless and confusing.

Fix `SettingsDialog` calling `setRequestedPanel(null)` inside a `useState`
lazy initializer (zustand setter during render -> React warning); move the
clear into a one-shot `useEffect`.

* ui/ux: opt Settings into OverlayScrollbars + caseless typography polish

Add an opt-in `useOverlayScroll` prop to `<Dialog>` that swaps the body's
native `overflow-y-auto` for `<OverlayScrollbarsComponent>` (autohide,
click-scroll, no native overlaid bars). SettingsDialog flips it on so the
long Layout / Color panels keep a visible, theme-aware scroll track on
Android / iOS webviews where native scrollbars auto-hide entirely. Other
short-modal callers stay on the native scrollbar.

Drop the `uppercase tracking-wider` SectionTitle styling for caseless
scripts and pair it with body-weight `font-medium` instead — those
typographic effects are no-ops on Han / Hangul / Devanagari / Thai etc.,
so a plain medium-weight body-size title reads more correctly than a
shrunken pseudo-uppercase one. SettingsRow / NavigationRow primary labels
follow the same rule (drop `font-medium` in caseless locales since the
inherited body weight already carries; CJK fonts bold poorly at body
size).

* ui/ux: SettingLabel primitive + KOSyncForm select polish + Tips alignment

Add `<SettingLabel>` primitive — caseless-aware row/field label that pairs
with `<SectionTitle>` (groups) for per-item labels. Cased scripts get
`font-medium`; caseless scripts (CJK / Arabic / Hebrew / Indic / Thai /
Tibetan) drop the weight since Han / Hangul / Devanagari etc. bold poorly
at body size. No font-size class so it inherits the `.settings-content`
14/16 cascade. Routed through `SettingsRow`, `NavigationRow`, and the
~12 ad-hoc inline `text-sm font-medium` callsites in AIPanel / FontPanel
/ ColorPanel / IntegrationsPanel / KOSync / Readwise / Hardcover forms.

Refactor KOSyncForm's Sync Strategy + Checksum Method rows onto the
shared `<SettingsSelect>` primitive — the inline 17-line div/select/
MdArrowDropDown chassis becomes a single SettingsSelect call with an
options array. Drops the unused MdArrowDropDown import and ~25 lines.

Fix Tips list-item alignment: callers traditionally pass `<li>` elements
(semantic) but the primitive was double-wrapping into `<li><span><li>...</li></span></li>` — invalid HTML, and the inner `<li>`'s
`display: list-item` broke line-wrap alignment on multi-line items.
Unwrap caller `<li>` to its content; add `flex-1` on the text span so
wrapped lines align under the first line instead of falling back to the
bullet column. Bullet container switches to `h-[1.4em]` so it tracks the
text line-height and pins to the first line's optical center via
`items-center` regardless of how much the content wraps.

DESIGN.md §5 typography updated to point primary-label callers at
`<SettingLabel>`.

## 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
pnpm test:browser # Browser tests (Chromium via Playwright)
pnpm tauri:dev:test # Start Tauri app with webdriver
pnpm test:tauri # Run Tauri integration tests
# Linting & Formatting
pnpm lint # Biome (linter) + tsgo (type check)
pnpm format # Prettier (runs from monorepo root)
pnpm format:check # Check formatting without writing
# Rust
pnpm fmt:check # Check formatting Rust code (src-tauri)
pnpm clippy:check # Lint Rust code (src-tauri)
```
### Source Layout
| Directory | Purpose |
| ----------------- | ------------------------------------------------------------- |
| `src/app/` | Next.js App Router pages and API routes |
| `src/components/` | React components (reader, settings, library, assistant, etc.) |
| `src/services/` | Business logic: TTS, translators, OPDS, sync, AI, metadata |
| `src/store/` | Zustand state stores |
| `src/hooks/` | Custom React hooks |
| `src/libs/` | Document loaders, payment, storage, sync |
| `src/utils/` | Pure utility functions |
| `src/types/` | TypeScript type definitions |
| `src/context/` | React Context providers (Auth, Env, Sync, etc.) |
| `src/workers/` | Web Workers for background tasks |
| `src-tauri/` | Rust backend: Tauri plugins, platform-specific code |
### Path Aliases (tsconfig)
- `@/*``./src/*`
- `@/components/ui/*``./src/components/primitives/*`
### Rust Backend (`src-tauri/`)
Platform-specific code lives in `src-tauri/src/{macos,windows,android,ios}/`. Custom Tauri plugins are in `src-tauri/plugins/`.
## Git Worktrees
Always use `pnpm worktree:new <branch-name|pr-number>` to create worktrees. Never use `git worktree add` directly — the script handles submodule initialization (simplecc WASM, foliate-js), dependency installation, `.env` copying, vendor assets, and Tauri gen symlinks that are required for lint and tests to pass.
```bash
pnpm worktree:new feat/my-feature # New branch from origin/main
pnpm worktree:new 3837 # Checkout PR #3837 with push access to fork
```
## 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.
### Design System
UI/UX rules — surface tiers, action vocabulary, settings primitives (`BoxedList`, `SettingsRow`, `SettingsSwitchRow`, `SettingsSelect`, `NavigationRow`, `Tips`, etc.), boxed-list anatomy, RTL conventions, e-ink overlay, and anti-patterns — live in [DESIGN.md](DESIGN.md). Codify recurring decisions there so they persist for the team and future contributors. Reach for the primitives in `src/components/settings/primitives/` instead of inlining chassis classes.
### E-ink mode
Every new UI widget must look right under `[data-eink='true']`. E-ink screens have no shadows, no gradients, slow refresh, and need crisp 1px borders for delineation. The conventions live in `src/styles/globals.css` — reuse the existing classes instead of inventing new ones:
- **Surfaces / inputs** — add `eink-bordered`. In eink mode it swaps to `bg-base-100` + 1px `base-content` border. Use it on inputs, custom button backgrounds, ghost-styled cancel buttons, and any container that needs a visible boundary.
- **Primary action buttons** — add `btn-primary` (alongside whatever Tailwind classes you use for color themes). The `[data-eink] .btn-primary` rule inverts to `base-content` bg + `base-100` text so the primary CTA stays distinct from secondary actions.
- **`.modal-box`** picks up no-shadow + 1px border automatically; dialogs that use it don't need additions.
- **Don't rely on color/shadow alone for hierarchy.** Two same-tone buttons differ only by hover on color themes, and hover doesn't exist on e-ink touchscreens. Pair a borderless ghost (cancel) with a solid CTA (submit) so eink can invert one without flattening the difference.
When in doubt, toggle E-ink in Settings → Misc and check. The rules in `globals.css` cover most cases automatically, but composite components (custom buttons, layered cards) often need `eink-bordered` on the right element to stay legible.
