/**
 * Personal OS — Bootstrap 5.3 override + components layer
 * ─────────────────────────────────────────────────────────
 * This file simulates what the production Sass build would emit:
 *   1.  Token CSS custom properties (mirrors Bootstrap's --bs-* vars where they exist)
 *   2.  Overrides of Bootstrap defaults that conflict with the design brief
 *   3.  Custom components Bootstrap has no equivalent for
 *
 * In production:  scss/main.scss → tokens → overrides → bootstrap → components.
 * In this prototype we load Bootstrap's compiled CSS first, then this file,
 * with selectors specific enough to win.
