   KARFOOK — Shared design tokens & components (multi-page)
   Theme: Chow Sang Sang / Chow Tai Fook goldsmith luxury —
          espresso #17110C, ivory #F7F1E3, antique-gold #C6A254,
          bronze #AD7A34, deep-red #8C2232 accents.
   Type: Fraunces (display) / Inter (body) / JetBrains Mono (utility)

   Shared across: index.html, memorial.html, products.html, prebook.html.
   Extracted from the original single-page KarFook-preview so every page
   inherits the same espresso/cream/amber language, nav and footer.
