/* Mini App — Hebrew RTL form for the miluim bridge.

   Layout strategy: mobile-first, single column, generous tap targets
   (≥44px), no fixed footer (Telegram renders its own MainButton at the
   bottom; we leave bottom padding so content doesn't slip under it).

   Theming: every color comes from a Telegram theme variable. The bot's
   user gets light or dark automatically, matching whatever theme they
   set in Telegram Settings → Appearance. Fallbacks are baseline-safe so
   the app still renders if Telegram ever ships a new theme variable
   without warning. */
