- Set backdrop z-index:0 and content z-index:1 to fix backdrop covering
modal content within the stacking context
- Force reflow between removing hidden and adding open class so CSS
opacity transition fires correctly
- Add transitionend listener + setTimeout fallback to restore hidden
class after close animation completes
- Override flex:1 on modal footer buttons to prevent full-width stretch
- Add min-width to modal size variants for consistent sizing
- Add 23 tests covering open/close lifecycle, keyboard, and destroy
