/* Billow design system - adapted from Dipayan's feature/frontend (PR #1) tokens; light theme derived 2026-10-17.
   Rules that hold everywhere: logical properties only (the page mirrors in Arabic); weights 400 and 700 only;
   every control is at least 3rem tall; every text pair is >= 4.5:1 and every control edge >= 3:1 in both themes.
   Theme: tokens on :root are the light theme; dark follows the phone (prefers-color-scheme) unless
   html[data-theme="light"] is set, and html[data-theme="dark"] forces dark. No Web Awesome: this file styles every control. */
