/* Ayahwise: mobile-first styles.

   Brand system (full guidelines: docs/ARCHITECTURE.md, "Design system")
   - Mark: the ayah verse marker holding a lamp flame (app/branding.py draws it).
   - Colour: Mushaf green #0A3D11 is the anchor, lamp gold #E0BA22 is the light
     (reward, progress, the flame). Neutrals are tinted green so greys never clash.
     Blue is not a brand colour any more: it appears only among the game tiles.
   - Roles: green = main actions, links, focus and success; gold = reward,
     progress, hints ("light") and the main action on green or dark surfaces;
     ink = selection.
   - Type: Delius (display: wordmark, headings, celebrations) for warmth,
     Figtree (interface and reading) for clarity and trust, Amiri Quran for verses.
   - Shape: pill buttons and chips; inputs 14px; answer options 16px; cards 24px.
     Buttons keep a small tactile edge and press down.
   - Light and dark themes follow the system setting.
