/*
 * সহজ's chamfered "angular card" component layer.
 *
 * Ported from the-rationality-lab/assets/rl-angular-cards.css (kept as an
 * untouched reference copy in git history — see
 * ratlab_theme_implementation_plan.md Phase 0.2) with two deliberate
 * changes from the original:
 *   1. Every hardcoded #000/#fff is replaced with সহজ's own --sohoj-*
 *      tokens (brand.css), so these components inherit the light/dark
 *      toggle automatically instead of being permanently black-on-white.
 *   2. Borders are 2px, not RL's 1px, matching brand.css's existing
 *      "2px hard borders, never 1px" convention (A3a mechanics note) so
 *      this new component layer reads as one system with the rest of the
 *      site rather than a visibly different weight bolted on.
 *
 * The chamfer amount itself (--sohoj-cut) is defined once in brand.css so
 * this file and any future one agree on it.
