English stays the default; Czech is a full translation. Only the app chrome is translated - notes and generated decks keep their own language, which is a core feature, not a setting. i18n - lib/i18n-dict.ts: flat en/cs dictionaries (441 keys each), translate() and translatePlural() with real Czech plural rules (1 sada / 2-4 sady / 5+ sad). English is the default and the fallback for a missing key. - lib/i18n.ts: browser store (freezmo.locale.v1), useI18n() hook, and the x-freezmo-locale header. The hook's t/plural are bound to the locale React is rendering with, so the first client render matches the server HTML and then re-renders in the stored language; module-level t is only for event handlers and non-React helpers. - <html lang> follows the choice (inline script + setLocale). UI - Settings -> Language segmented control (English / Cestina), plus an EN/CS button on the key gate for first run. - Every screen translated: sidebar, header, tab bar, library, deck cards, folder bar, create flow, all seven activities, study chrome, results, settings + health panel, API-key gate and help, install sheet, offline and the deck-not-found page. - Plural-aware counts everywhere (decks, folders, activities, runs, photos, documents, pages, words, wrong attempts). Server - API routes and guards (generate, grade, health, http-guard, rate-limit, ollama error mapping) answer in the request's language, so error cards and the health panel never fall back to English mid-sentence. Fixes - A hydration mismatch when a non-default locale was stored silently dropped the .dark class after hydration; render-time t() is now bound to the hook's locale (UploadScreen.describeExtraction, ResultsScreen.answerFor, DeckCard's folder fallback). - Bumped the service worker cache to freezmo-v4 for this deploy. Tests: i18n 27/27 (gate toggle, persistence, html lang, Czech plurals, settings switch) and a rebuilt regression suite 72/72 (English default, library, create, all 7 activity types, results, settings, install sheet, offline, PWA, security, Czech smoke).
