/* ============================================================
   Benefits Access Portal — Component Styles
   Depends on: tokens.css (must be loaded first)
   ============================================================
   These styles target the existing HTML IDs and classes in
   index.html exactly as they are, so no structural changes are
   needed to activate the redesign — just swap the <style> block
   for two <link> tags.

   Design principles applied:
     - Generous space (stressed readers need breathing room)
     - High contrast (WCAG AA throughout)
     - Body text ≥ 16 px (17 px preferred)
     - Touch targets ≥ 44 × 44 px
     - Responsive: fluid up to 800 px max-width, full-width on mobile
   ============================================================ */
