Accessibility instructions

Target WCAG 2.2 AA on every surface we ship.

  • Use semantic landmarks; one <h1> per view, no skipped heading levels.
  • All interactive controls reachable and operable by keyboard.
  • Visible focus styles — never outline: none without a replacement.
  • Colour contrast ≥ 4.5:1 for text, ≥ 3:1 for UI and large text.
  • Respect prefers-reduced-motion; gate non-essential animation.
  • Label every input; associate errors with aria-describedby.
