Accessibility

WCAG 2.2 AA is the floor. AAA where the cost is small. We treat accessibility as a correctness problem, not a feature.

Contrast

• Body text ≥ 4.5 : 1 (AA). Default body is 19.6 : 1 (AAA).
• Large text (≥ 18.66 px bold or ≥ 24 px regular) ≥ 3 : 1.
• UI components and graphical objects ≥ 3 : 1.
• Focus indicators ≥ 3 : 1 against both the component and its background.

Focus & keyboard

• Every interactive element is reachable and operable with a keyboard. :focus-visible is required, never outline: none without a replacement.
• Focus order matches visual order. Skip links lead to the main landmark.
• Target size is ≥ 24 × 24 CSS pixels (WCAG 2.2 — 2.5.8).

Motion

• Honour prefers-reduced-motion. We collapse durations to 0.01 ms in the global stylesheet.
• No parallax or large auto-scroll without an explicit user toggle.

Forms

• Every input has a programmatic label. Placeholder is never a label.
• Error messages reference the field by id and are announced via aria-describedby.
• No CAPTCHA without an accessible alternative (WCAG 2.2 — 3.3.8).
