The deliberate offline mode is now visible: an installed web-PWA user with a confirmed email can switch to offline in Settings, and the header turns blue with an "Offline" chip. (Network gating, the dict preload, the offline lobby + local-game creation, and the service-worker precache follow in later Phase C steps.) - offline.ts / offline.svelte.ts: a sticky, device-scoped reactive offline flag (offlineMode), distinct from connection.svelte's transient reachability signal, with the pure persistence + readiness helpers (offlineReady / missingDicts) unit-tested. - Settings.svelte: an Online / Offline toggle, shown only for an installed web PWA with a confirmed email (the SW-launch + durable-account preconditions). - Header.svelte: a blue-tinted nav (color-mix from the accent, so it tracks light/dark and a Telegram theme override) + an "Offline" chip while offline; the deliberate mode suppresses the transient "Connecting…" indicator. Behaviour-preserving online (the toggle is hidden and offlineMode is false there; e2e 196 green). App entry stays within its size budget (111.6 / 112 KB gzip).
