Frontend context for LLM

Entrypoint main.jsx; routes/lazy in App.jsx; pages in pages; UI in components; readers in readers; API in lib/api.js.

Remote state: TanStack Query. Navigation/filters: URL. Fallback/progress: localStorage + sync API. Scroll: sessionStorage. Offline: Cache Storage + IndexedDB. Theme: Context.

Library focuses navigation on the sidebar/drawer and tree of categoryPath; do not reintroduce global tabs in the content. History is “Pick up where you left off”; /continuar only redirects.

Readers share shell, dock, progress, budget, and cleanup. Preserve desktop/mobile/touch, full viewport and PDF worker Vite .js. Service Worker should not automatically cache books.

Minimum tests for frontend: npm run test:frontend, build; reader/PWA requires E2E and performance.
