Focus-Trapped Modal Kit: A bare-bones modal foundation whose whole point is disciplined keyboard behavior: it traps focus while open and restores it precisely on close, wrapped in a tilt-in entrance.

react, vue, svelte, astro, html

### Which frameworks are available for Focus-Trapped Modal Kit?

These are source observations. Verify accessible names, focus order and keyboard behavior in the composed page.

### How does Focus-Trapped Modal Kit handle reduced motion?

Focus-Trapped Modal Kit reads the motion preference in its React source through useReducedMotion(). Preference-dependent expressions in index.tsx: duration: reduced ? 0 : 0.18; enter: reduced ? \{ duration: 0.14 \} : \{ type: "spring", stiffness: 260, damping: 24, mass: 0.85 \}; exit: reduced ? \{ duration: 0.1 \} : \{ duration: 0.16, ease: \[0.4, 0, 1, 1\] \}. Check the full implementation, shared styles and selected port with reduced motion enabled; these observations do not establish that every animation stops.
