   iThuba design system (v2)
   Load this LAST on every page:  <link rel="stylesheet" href="/css/ithuba-theme.css">
   (employer/ and admin/ pages use ../css/ithuba-theme.css)

   Component layer only: layout, cards, forms, badges, alerts, tables, footer, mobile fixes.
   It has NO colours, fonts or radii of its own. Every token below points at iThuba's
   existing variables: employer/tokens.css on employer-portal pages (checked first), then
   styles.css on worker and admin pages, then a hex fallback.
   Base element rules use :where() so page CSS can still override; .it-* components are explicit.
