Add a vertical-scroll continuous mode to the reader alongside the existing single-page mode. A segmented toggle in the reader top bar switches between them; in continuous mode a gap selector (None/Small/Medium/Large → 0/12/32/64px) controls the spacing between stacked pages. Settings page mirrors the same controls. Backend: new user_preferences table (one row per user, lazily inserted, ON DELETE CASCADE) and GET/PATCH /api/v1/auth/me/preferences gated by the existing CurrentUser extractor. Allowed values are enforced both by API validation and table-level CHECK constraints. Eight integration tests cover defaults, persistence, partial updates, validation errors, auth, per-user isolation, and cascade. Frontend: a new preferences store mirrors the theme-store pattern with a localStorage shadow so anonymous browsers get a consistent experience and logged-in users don't flash defaults while the server response is in flight. Server values that the frontend doesn't recognize (forward-compat) are ignored rather than poisoning the UI; non-401 PATCH errors revert the optimistic local update; logout clears the shadow so user A's settings don't follow user B on a shared browser. In continuous mode native scrolling handles Space/PageDown/arrows; Home/End remain wired and call scrollIntoView() so jumping to chapter bounds stays one keystroke. Single-page mode (chevrons, arrow-key pagination, next-page preload) is unchanged. Versions bumped 0.13.0 → 0.14.0 in lockstep. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
