Annotating Wireframes: Edge Cases and Functional Logic

A wireframe without annotations is only half a blueprint:

Annotations provide crucial interaction context for developers:

• Dynamic Data Behavior: 'If user has 0 orders, display Empty State Illustration B.'
• Character Limits: 'Project title truncates with ellipsis (...) after 42 characters.'
• Validation Rules: 'Submit button remains disabled until password meets 8-character regex.'
• Edge Conditions: 'How does this container respond when loaded with 500 items vs. 0 items?'
