/* =============================================================================
   GETSITEGO ADMIN — shadcn/ui design system, ported to plain CSS.

   shadcn/ui is a React component collection; the admin is server-rendered PHP,
   so what is reproduced here is the system underneath it: the HSL token layer,
   the radius scale, the focus ring, and the component recipes (button, card,
   input, table, badge, alert, tabs). Values are shadcn's "blue" theme, which
   lands close to the GetSiteGo brand.

   Self-contained on purpose — the admin no longer loads the marketing site's
   stylesheets, so restyling the site cannot disturb the admin, or vice versa.
