Paginator & Scroll

• Reading ruler: line-aware frame-offset map; vertical-rl backwards #4865
• Vertical-rl horizontal pagination (#624) — horizontal inputs + two-phase slide; rtl gated !vertical
• Slide/curl turn styles via VT (#555) — VT turns gated on nested-VT-groups support (iOS 18 WebKit crashes despite having the API); Tauri fallback = CapturedPageTurn capture pipeline (WebGL mesh curl + flat canvas slide, full-gridcell capture, instant nav = drop animated); MERGED #4940 (2026-07-05), verified live mac/iOS/Android (mobile = JPEG capped 2x, PNG was 1.5s/turn); Win/Linux capture still open
  • Captured turn ignored instant-highlight hold — captured slide/curl swipe path (app interceptor, no-swipe set) didn't honor renderer.scrollLocked; fix = foliate get scrollLocked() + gate useCapturedTurn move on it (push/VT-slide already gated); PR#5000 + foliate#51

Library Fixes

Architecture & Patterns

• foliate-js submodule at packages/foliate-js/; multiview paginator preloads adjacent sections
• Turso "concurrent use forbidden" op_lock async mutex
• Markdown: .md support #774; resume position #4862
• Style: getLayoutStyles() always, getColorStyles() when overriding; transformStylesheet() rewrites EPUB CSS
• TTS #ttsSectionIndex; insets: native plugin → useSafeAreaInsets → styles; Dropdowns DropdownContext
• Stale settings closure: persist useSettingsStore.getState().settings (#4780)
• Page margins not live #4898 in-place mutation froze memo
• Foliate touch-listener capture phase
• iframe cross-realm instanceof duck-type 'closest'
• Virtuoso + OverlayScrollbars
• Design system → DESIGN.md never pl/pr/ml/mr (RTL)

Workflow & Feedback

• Commit messages English-only no CJK, no em/en dashes
• PR flow: rebase onto origin/main; fresh branch per PR; always pnpm worktree:new; commit locally, don't push until confirmed
• Test file filter pnpm test <path> no --
• No test seams in prod · no lookbehind regex
• i18n: en plurals manual; i18n:extract prunes keys
• Dependabot transitive fixes pnpm-workspace.yaml overrides:
• Upgrade gstack locally
