/*  ============================================================================
    E-Menum — WCAG 2.2 AAA Accessibility & High-Contrast Stylesheet
    Applied ONLY to marketing/CMS pages (via marketing.html layout).

    Goals:
    - WCAG 2.2 AAA contrast ratios (7:1 normal text, 4.5:1 large text)
    - Elderly-friendly font sizing (base 18px, generous line-height)
    - Hybrid high-contrast UI (not dark, not light — optimized readability)
    - Skip-to-content link
    - Focus indicator (3px solid outline)
    - Reduced motion support
    - Touch targets min 44x44px
