Skip link
Each HTML page places a skip link before the header and targets `#main-content`.
Accessibility statement
The founding flow is keyboard-first and motion-light.
WCAG 2.2 AA is the local target. Static pages expose skip links, visible focus, alt text, semantic landmarks, and reduced-motion behavior.
Keyboard contract.
Focus ring
Links, buttons, fields, summaries, and custom focus targets share a 3px focus outline.
Keyboard parity
Native controls are preferred, and custom controls must preserve tab order and escape behavior.
Motion contract.
Transitions are capped at 160ms in normal mode and reduced to 1ms when `prefers-reduced-motion: reduce` is present.
Alt-text contract.
Raster and SVG assets identify actual product, gathering, governance, trust, or outcome state. Decorative-only image usage is avoided on launch-critical pages.
Local audit gate.
