/* ===========================================================================
 * admin.css — branded super-admin theme (Story 5.3 / BIMERGE-57).
 * ---------------------------------------------------------------------------
 * Consumes the shared OKLCH design tokens (tokens.css — the single :root source,
 * also inlined into the React dashboard's application.css). Light app surface,
 * dark-teal header chrome (sidebar-* tokens), teal-primary actions, gold focus
 * ring, destructive-red errors.
 *
 * This is "classless" CSS: it targets bare HTML elements so the admin ERB views
 * need no markup classes (the one exception is .admin-header, added in
 * app/views/layouts/admin.html.erb). Colors are driven by var(--token); the only
 * non-token colors left are the documented green success-flash exception (no
 * "success" token exists in the brand set yet — see Story 5.3 Decisions).
 *
 * tokens.css is linked alongside this file in app/views/layouts/admin.html.erb
 * and registered in app/assets/config/manifest.js.
