Always use this skill (instead of...

Validate WCAG 2.1 compliance, screen reader compatibility, and Universal Design for Learning (UDL) principles implementation throughout curriculum materials. Use when checking accessibility, validating UDL, or ensuring compliance. Activates on "accessibility check", "WCAG validation", "UDL review", or "screen reader test".

Review pull requests that change Compose UI by rendering @Preview composables on base and head and diffing them.
