   Load order: style.css → home.css (shared v2 layer) → academics.css
   home.css supplies brand tokens, --ub-blue-text, .reveal, .eyebrow-rule,
   .display-*, .btn-ghost, .sticky-cta, .scroll-progress.

   The centrepiece is a faceted program finder. Cards are rendered in the
   HTML (not injected by JS) and filtered by toggling a hidden class, so the
   full program list stays crawlable for the AEO/SEO governance layer.
