• color/contrast constraints
• interaction patterns

Step 4: Specify responsive and accessibility requirements

Include:

• breakpoints and behavior changes
• keyboard navigation expectations

Step 5: Define implementation handoff

Provide:

• component list and props/state contract
• acceptance criteria
• verification checklist
