Accessibility

Accessibility is a design constraint, an engineering practice, and a shared review responsibility.

Keyboard

Every interactive element is reachable, operable, and visibly focused in a logical order.

Landmarks, headings, labels, tables, and dialogs communicate structure without visual styling.

Text and interactive boundaries meet WCAG AA across light and dark themes.

Transitions explain change, avoid vestibular triggers, and respect prefers-reduced-motion.

Labels describe outcomes, errors explain recovery, and instructions do not depend on color alone.

Targets have enough area and spacing for reliable input on small screens.

Test at 200% zoom with no horizontal page overflow.
Complete the primary flow using only a keyboard.
Verify names, roles, states, and announcements with a screen reader.
Check light and dark contrast, including hover, focus, disabled, and error states.
Confirm the experience remains understandable when motion is reduced.
