Semantic structure. Proper heading order, landmark regions, and lists, so the page is navigable by assistive technology.
Skip to content. A skip link lets keyboard users jump straight to the main content.
Keyboard operability. Every interactive element is reachable and operable without a pointing device, with visible focus states.
Reduced motion. Content is visible by default and does not depend on animation; where prefers-reduced-motion is set, motion and reveal effects are disabled.
Colour contrast. Text and essential UI are verified against WCAG AA contrast thresholds.
Images. Meaningful images carry descriptive alternative text; purely decorative images are hidden from assistive technology.
Responsive and zoom-friendly. The layout reflows across viewports and remains usable when text is enlarged.
