 * DEFERRED (follow-up passes — intentionally NOT done here to stay surgical):
 *   1. `.btn` is redefined in ~10 files (site.css, dv8-design-tokens.css, design-tokens.css
 *      a11y-btn, sandf-theme.css, auth-*.css, operations-portal.css, …). Unify into a single
 *      button component in a later pass; blind-merging risks visual regressions.
 *   2. Bootstrap AND Bulma are both loaded (see _Head.cshtml / _AuthLayout.cshtml). Removing
 *      either is high-risk without a full visual audit — keep both for now.
 *   3. Remaining raw slate/grey hex + multi-value/gradient brand hex are left for stylelint
 *      (.stylelintrc.json bans raw hex in wwwroot/**/*.css) to surface for migration to
 *      var(--neutral-*) / brand tokens.
