- Replace fixed font sizes with semantic Dynamic Type styles
- Hide decorative elements from VoiceOver with .accessibilityHidden(true)
- Add .minimumHitTarget() modifier ensuring 44pt touch targets
- Add AccessibilityAnnouncer utility for VoiceOver announcements
- Improve color contrast values in Theme.swift for WCAG AA compliance
