   AHMAD ACADEMY — Design system
   Consistent with the School Management System (SMS) HCI:
   - Deep indigo for navigation and primary actions (calm, trustworthy, WCAG AA contrast)
   - Warm amber for highlights
   - Soft lavender-grey canvas, rounded friendly cards
   - Inter (body) + Nunito (display) — same font stack as the SMS
   - Same component vocabulary: .btn-primary, .btn-ghost, .card, .chip, .badge
   - Same focus ring, skip-link, and visibility-of-system-status patterns
