Mobile Overflow Rescue
Prevents long, translated, or zoomed labels from disappearing off-screen for touch-first and constrained surfaces; it is designed to preserve hierarchy and reachability without covering content. Overflow recalculates into an accessible menu while preserving source order. The mobile and spatial navigation variant is specialized for touch targets, safe areas, and one-handed use constrain layout. Users can preserve hierarchy and reachability without covering content while understanding the current state, available choices, and resulting consequence.

Implementation field notes
Use mobile overflow rescue confidently.
The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.
Accessibility contract
- The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
- Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
- Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.
Integration plan
- Copy the standalone HTML and scoped CSS into an isolated page.
- Adapt primary wayfinding signal, spatial highlight, navigation surface, primary text through the Inspector.
- Connect the defensive JavaScript, then test every control with a keyboard.
- Review the result at 375, 768, 1024, and 1440 pixels before shipping.
