// A bottom sheet: a modal (Radix Dialog) that slides up from the edge, with
// the same focus trap, Escape and close button as Dialog. Drag the handle
// down to dismiss it:
// - Responsive gesture: the sheet follows the pointer 1:1 from the first
//   pixel; dragging up meets resistance.
// - Continuous gesture: the pointer is captured, so straying off the handle
//   keeps the drag alive.
// - Anticipation: past the threshold the handle stretches and says
//   "Release to close", so you know what letting go will do.
// - Cancelable gesture: it only closes on release past the threshold, or on
//   a quick flick (momentum: faster than 0.11px/ms on average); letting go
//   short of both springs back.
// - Friction, not walls: dragging up meets rising resistance.
// - One finger at a time: a second touch during a drag is ignored, so the
//   sheet never jumps.
