ryux-accessibility: Accessibility

Group UI · Delivery Gate area ACCESSIBILITY · RX-2.0. Levels are defined in ryux-core.

Accessibility is product quality, not an enhancement. Check:

• Semantics: real headings, landmarks, lists, buttons, links, labels.
• Keyboard: everything reachable and operable; focus order follows the visual order.
• Focus: visible on every interactive element; never removed without a replacement.
• Contrast: 4.5:1 for text, 3:1 for large text and component boundaries.
• Targets: at least 24×24px, preferably 44×44px on touch.
• Names: icon-only buttons and meaningful images have accessible names.
• Forms: labels tied to fields; errors tied to fields and announced.
• Color: never the only signal.
• Motion: honor reduced-motion settings.
• ARIA: only when native semantics cannot express it.
