   HUB THEME  —  shared "Choose Your Own" look (light / high-clarity)
   ───────────────────────────────────────────────────────────────────────
   Black text on a white background for maximum readability, with gold
   (Workspace) and teal (Learn) kept only as accents — coloured top bars,
   icon tiles and hover states — so the card families stay distinct.
   Playfair Display for headings, Cormorant Garamond for body text.

   Used by: index.html and the workspace pages
   (journal, tailored-practice, paper-submissions, memorisation).
