/* ============================================================
   Citizenship Practice — shared stylesheet (v3 Design Refresh)

   Design principles:
   - Adult ESOL and citizenship learners: calm, professional,
     welcoming. Think public library or community college, not
     government form or children's app.
   - Warm cream background — easier on the eyes than pure white,
     especially on phones in variable lighting.
   - Patina Green accent — trustworthy, warm, consistent with homepage.
   - Layered shadow system for visual depth.
   - 56px minimum tap targets throughout.
   - All color pairings meet WCAG AA contrast.
