   GLOW PATH — style.css
   Design tokens live as CSS custom properties on :root. app.js overwrites a
   handful of them (--tg-*) from Telegram.WebApp.themeParams at boot, so the
   chrome adapts to the user's Telegram theme while the game scene itself
   (the canvas) keeps its own deliberate night-sky palette — that palette IS
   the game's identity and shouldn't flatten to a generic light theme.
