/* Adventure Club, Phase 0 landing.
   Gallery-white aesthetic. System fonts only.
   - Light + dark theme via prefers-color-scheme.
   - rem-based sizing so user font-size adjustments scale the whole page.
   - Visible :focus-visible outlines + skip-to-content link for keyboard users.
   - WCAG AA contrast at small sizes (--faint bumped from #8a857c to #6a6258).
   - Reduced-motion defended even though no animations exist today. */
