Web interface guidelines review

When to use

• Reviewing a PR that adds or modifies UI components.
• Auditing an existing UI surface for token discipline, contrast, focus handling, and a11y.
• Writing or reviewing design specs that propose new components.
• After a Figma → code handoff, before merging.

When NOT to use

• Pure backend / non-UI PRs (skill won't fire on a server-route change).
• Marketing-only landing pages with bespoke design that intentionally lives outside the system.
• Prototype code explicitly labeled as throwaway.

The review checklist

Apply each section in order. Stop and flag at the first failure in each section.
