Web Interface Guidelines

Concise rules for building accessible, fast, delightful UIs. Use MUST/SHOULD/NEVER to guide decisions and reviews.

How to Apply

• Prioritize MUST items first; NEVER items are hard constraints.
• When reviewing, scan each section and confirm every MUST is satisfied.
• If a guideline conflicts with product requirements, surface the conflict explicitly.
