Implementation field notes
Use alert page alert confidently.
The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.
Accessibility contract
- The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
- Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
- Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.
Integration plan
- Copy the standalone HTML and scoped CSS into an isolated page.
- Adapt trust signal, recovery highlight, feedback surface, primary text through the Inspector.
- Connect the defensive JavaScript, then test every control with a keyboard.
- Review the result at 375, 768, 1024, and 1440 pixels before shipping.
