   - Palette is deep indigo + turmeric-yellow + clay red, on a warm
     near-white paper background — a nod to indigo dye and terracotta
     craft traditions from West Bengal, without leaning on a stock
     "cream + terracotta" template.
   - Display face: Fraunces (soft-serif, characterful, used for the
     logo wordmark and headings only).
   - Body/UI face: Inter (neutral workhorse for everything else).
