Reported directly: the only way to close the bottom sheet was tapping
the scrim, and the instinctive swipe-it-down gesture fell straight
through to the browser's own pull-to-refresh instead - nothing was
telling the browser this app's own code owned that gesture.
touch-action: none on the scrim and the (now real, not just visual)
grabber handle stops the browser's default touch handling from
kicking in there at all; overscroll-behavior: contain on the sheet
itself stops a drag that hits its own scroll boundary (the library
grid can run taller than the sheet's 75vh cap) from chaining to the
page underneath. The grabber's small 36x4px pill now sits inside a
much bigger invisible touch target that actually drags the sheet
(pointerdown/move/up, 1:1 tracking, snap back under 90px or close past
it) - scoped to the grabber alone, not the whole sheet, so the
library grid's own taps/scroll keep working untouched.
