/* tgcast Mini App — mobile-first, Telegram-native.
 *
 * Every colour comes from Telegram's theme variables with a fallback, so the
 * app matches whatever theme the user runs — including the ones Telegram adds
 * after this ships. Hard-coding a palette is the fastest way to make a Mini App
 * look like a website that wandered into a chat.
 *
 * Sizing rules that matter on a phone:
 *   - 44px minimum tap target, everywhere, no exceptions;
 *   - 16px minimum font size on inputs, or iOS zooms the page on focus;
 *   - safe-area insets at the bottom, or the CTA hides under the home bar.
