Semantic HTML
Use headings in order, real buttons for actions, links for navigation, labels for controls and landmarks for major page regions.
Keyboard & focus
Every interactive control must be keyboard reachable with a visible focus indicator. Custom interactions should provide expected arrow-key behavior when appropriate.
Motion
Animation should clarify state rather than distract. Versa enhancements respect prefers-reduced-motion wherever motion is nonessential.
Contrast
Default text, controls and focus states are designed for strong readability. Recheck contrast whenever project colors override Versa tokens.
