/* Staff Docs Portal: Policies & Help and the admin panel.
   Brand comes from the host site's CSS variables (DC: assets/css/main.css),
   with neutral fallbacks so the module still renders on a site without them.
   Every selector is namespaced .sd- so nothing leaks into the host page.
   Secondary text uses --ink-mid, not --ink-soft or --ink-xsoft, to keep small
   text at 4.5:1 or better on white (WCAG 2.1 AA). */
