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

# 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)

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.

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 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 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. 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.
