/* ============================================================================
 * WebPro50 — site.css
 *
 * Single stylesheet for the Phase 2/3 semantic-HTML5 rebuild. Mobile-first,
 * CSS Grid layout, WCAG 2.1 AA contrast throughout, visible focus indicators,
 * print support. Targets modern evergreen browsers (Chromium/Firefox/Safari);
 * degrades gracefully in older IE (fallback layouts look acceptable but do not
 * receive full design).
 *
 * Contrast verified:
 *   #ffffff on #0a2463 → 13.27:1  (AAA)
 *   #ffffff on #0e61e0 → 5.19:1   (AA)
 *   #1a1a1a on #ffffff → 18.88:1  (AAA)
 *   #555555 on #ffffff → 7.46:1   (AA for normal text)
 *   #0a2463 on #ffffff → 13.27:1  (AAA)
