Skip link + focus-ring strip
Keyboard path demo. Not live masterengine.ai. Not kernel source of truth.
Evidence gate
Automated findings alone (scan export / AI paste) are not enough. Keyboard/focus attestation is required before any pass claim.
- Skip-link reaches main
- Tab order hits 3 controls
- :focus-visible visible
- Escape/close if any overlay
Demo controls (A / B / C)
Three keyboard-reachable controls. Tab to each; Enter/Space toggles state. No overlays on this page — Escape N/A.
Also: ?shot=focus force-visible focus rings for headless screenshots.
