/* Ports the mobile app's visual language to the web.
 *
 * The two products already shared a brand -- same #A40021 crimson, same Worstveld display face
 * for the wordmark. What the web lacked was everything underneath it: the app builds every
 * surface from soft #F6F6F6 panels at a 12px radius with no border and no shadow, at a much
 * larger type scale, while the web was rendering stock Bootstrap defaults.
 *
 * This file is loaded LAST so its :root block wins over Bootstrap's. It is organised as:
 *   1. Tokens              -- lifted from the app's constants/colors.ts + tailwind.config.js
 *   2. Bootstrap remap     -- expresses the tokens through Bootstrap's own --bs-* variables,
 *                             so the ~134 existing .card sites and every .btn restyle themselves
 *   3. Component overrides -- where a Bootstrap default is not close enough to the app
 *   4. New components      -- patterns the app has that Bootstrap has no equivalent for
 *   5. Legacy aliases      -- .btn-brand / .hero-section / .callout etc., so the pages that have
 *                             not been rebuilt still inherit the redesign
 *
 * Source of truth for every value is the app at ../kotoba-kards. */
