- Add sheet drag handle (::before pseudo-element) and closing animation (sheet-out keyframe) for mobile < 768px in layout.css
- Add prefers-reduced-motion support disabling all modal animations
- Refactor closeModal() to extract _doClose() and play slide-out animation on mobile before removing the overlay
- Add _wireSheetSwipe() for touch drag-to-dismiss (threshold 80px)
- Extend trapFocus() Enter handler: advances focus through inputs/selects and triggers primary button on last field
