web: /login + /auth/callback routes + auth context + config reader
- web/src/lib/config.ts: readConfig() reads window.__LETHE_CONFIG__ (IF1),
converts client_id -> clientId, throws on absent config (GPC6)
- web/src/lib/authContext.tsx: AuthProvider subscribes to tokenStore, parses
ID token name claim, exposes signIn/signOut/reportAuthError via context;
hasBeenAuthenticated flag supports IV7 cold-vs-session distinction
- web/src/routes/login.tsx: /login route calls signIn(return_to) on mount
- web/src/routes/auth.callback.tsx: validates state+TTL, exchanges code via
raw fetch to OP /token (allowed exception), stores access_token via
tokenStore.set, anti-loop guard using countCallbackFailures (IV6)
- web/src/routes/__root.tsx: wraps tree in AuthProvider above
KeyboardCursorContext
- web/src/routeTree.gen.ts: regenerated by Vite with /login and /auth/callback
- internal/server/web/dist/index.html: rebuilt artifact with new asset hashes
