Owner review-pass rework of the landing page:
- Rename the per-language Telegram link build var
VITE_TELEGRAM_LINK_EN/_RU -> VITE_TELEGRAM_GAME_CHANNEL_NAME_EN/_RU
(it carries a channel username; the landing builds https://t.me/<name> --
the same channels the connector posts to via TELEGRAM_GAME_CHANNEL_ID_*).
- Language switcher -> a globe icon dropdown (flags + names), saved + synced
to the app prefs.
- Theme switcher -> a sun/moon icon toggle, ephemeral (follows the system
scheme, no auto, never persisted) -- galaxy-game style.
- Drop the "Play in browser" CTA (no standalone-web onboarding yet).
Docs: FUNCTIONAL(+ru), PLAN, deploy + ui READMEs.
Close out Stage 17 round 6:
- Landing page at / — one Vite build with two entries (index.html = game
SPA, landing.html = a lightweight landing reusing the theme/i18n/
aboutContent leaf modules, not the app store).
- Move the web game SPA to /app/; the Telegram Mini App stays at /telegram/
(gateway webui.Handler(stripPrefix, indexName): landing at /, SPA at /app/
+ /telegram/). Per-language "Play in Telegram" link via new
VITE_TELEGRAM_LINK_EN/_RU build vars (button hides when unset).
- Cache headers: hash-named /assets/* immutable, HTML shells no-cache (the
go:embed zero modtime emitted no validators, so the client re-downloaded
the whole bundle every launch).
- Live-stream 15s abort fix: an immediate heartbeat on open + a 10s default
interval (the first tick at 15s raced the edge idle timeout -> reconnect
storm).
PLAN/ARCHITECTURE(§13)/FUNCTIONAL(+ru)/gateway+ui+deploy READMEs updated;
round 6 closed. Tests: gateway webui/connectsrv units, ui landing unit + e2e,
full e2e (60) green.
