/* ============================================================
 * MMB Mini App — visual style
 *
 * Design notes:
 * - Telegram theme variables drive the palette: the app blends with
 *   whichever Telegram client the user is in (light/dark/custom).
 * - Hero shows live album art; the same image is used as a heavily
 *   blurred backdrop behind the whole UI (`#bg-art`) for a Spotify-ish
 *   ambient look that still respects Telegram's bg color underneath.
 * - All animated transitions use cubic-bezier(.2,.7,.2,1) (UI ease).
