/*
 * app.css: the Mini App's look (spec-v2 E). The arrangement is the owner's mock-up;
 * the visual language is Telegram's own, so the page feels native: its theme
 * variables (--tg-theme-*, set by telegram-web-app.js or, without it, by app.js from
 * the launch parameters) drive every base colour in light and dark themes; the --fb-*
 * values are only the fallbacks outside Telegram (prefers-color-scheme).
 * Soft cards on the secondary background, subtle separators, an 8px spacing grid,
 * one large number per screen, tabular figures where digits tick. Accent colours are tints over the
 * section colour, so they stay readable on any theme. The fonts are served from here
 * (fonts/, cached for a year): B Yekan for the app, B Mitra for the answers of the
 * questions sheet. Both are used for Persian only: Latin text (TON, links, addresses)
 * is in the system font that follows them in the stack.

   unicode-range: the Arabic script, its marks and the space, nothing else. These fonts draw
   Latin digits as Persian ones, which would turn an invite link's "r_k7m2" or an address
