/* ============================================================
   about.css
   Page-level styling for about.html only. Loaded AFTER css/style.css —
   additive only, reuses the shared editorial design system (.kicker,
   .stats, .stat-card, .steps, .step, .cta-band, .btn, .container,
   .reveal, .uc-num) for consistency. Introduces new "ab-" prefixed
   classes so nothing here collides with rules that other pages/scripts
   depend on. Colors are pulled exclusively from the CSS custom
   properties defined in style.css so light/dark mode both keep working.
