+[fix] A finger that catches a settling BottomSheet and holds it no longer starts selecting the sheet's text. Where a long press fires `selectstart`, the sheet cancels it and changes no style, so nothing repaints; on iOS, whose long press fires none, selection and the touch callout are off on the sheet while a finger holds or drags it.

+[fix] Under a finger, on every touch device, a BottomSheet's scrim follows the sheet the way an iOS sheet's dim does. Dragged below its shortest detent, the dim thins in a straight line with the sheet's position and clears only when the sheet reaches the bottom of the screen; it used to clear 40 % of the shortest detent's height below it. A standalone sheet's dim follows the finger at once instead of easing behind it over the theme's medium duration (410 ms by default). When the sheet settles or is flung away, the dim rides the same spring frame for frame, on the compositor. Under a mouse the dim is unchanged. A peek detent's lighter scrim is unchanged.

+[fix] A BottomSheet opened or closed under a finger, on every touch device, moves the way an iOS sheet does: on iOS's sheet spring, from below the screen to its detent and back, with the scrim fading on the same spring, on the compositor so a busy page doesn't stall it. Under reduced motion it fades in and out in place, in 200 ms or less, instead of sliding. While it presents, touches are held and a close waits for it to land, as on iOS.

+[fix] A BottomSheet let go under a finger moves the way an iOS sheet does, on every touch device. It settles on the stop nearest where its speed carries it, a quick flick going at least to the next stop, with gone below the screen counting as a stop (one moving back toward where the drag began returns there), and on iOS's own release spring, starting at the finger's speed instead of from a standstill; under reduced motion it fades in place instead. Under a mouse a release keeps today's rule and the theme's duration and easing, on the same release speed as a finger's: a mouse held still for more than 40 ms before the release no longer throws the sheet. Everywhere, the settle runs on the compositor, so a busy page no longer stalls it, and a finger can catch the sheet while it settles, on iOS too. The finger's speed is read from when each touch happened rather than when the page got to it.

+[fix] A BottomSheet drag follows the finger the way an iOS sheet does. The sheet stays exactly under the finger between detents, instead of being pulled toward a nearby detent in the last 40 px; the release picks where it lands. Pulled up past its tallest detent, it stretches by UIKit's rubber band, no farther than the space it reserves below. This applies to a finger or a pen where the primary pointer is coarse; a mouse, and any drag where the primary pointer is fine, is unchanged: it still eases onto a nearby detent and stretches a little past the tallest one.

With the `{stylexOptions}` form (the one Storybook uses), a file that read only constants from a `.stylex.ts` module lost that import once StyleX compiled it, so the constants never reached the CSS: a constant used as a media-query key failed the build ("Invalid empty selector") and one used as a value shipped as a custom property nothing declares. In either form, a constant defined on the other side of the layer split, or in an Astryx package (compiled with the library class-name prefix) and read from an app file (compiled with its own), stayed unresolved. The `{stylexOptions}` form now passes StyleX `treeshakeCompensation: true` by default (before, its babel pass ran with StyleX's default, `false`), as the plugin form already does; pass `treeshakeCompensation: false` in `stylexOptions` to restore the old behavior.

+[chore] Internal: the gesture host becomes the one document-level touch owner: the finger count, touch gates, and a kept press for continuous-tracking controls, whose element gets `touch-action: manipulation` where the pointer is coarse. A scroll lock's page hold and the finger-scroll watch keep their own listeners and ask the host only about the touches it owns. A second finger fails a one-finger pan that has not claimed, so the page can pinch. A scroll-edge pan holds a lone finger from the first move that pulls away from an edge every scroller under it is at, so those moves are cancelled before it begins; with a second finger anywhere on the screen the page keeps its pinch. The host follows the primary pointer when it changes; what it attaches under a fine pointer is in the every-pointer changeset (`gestures-every-pointer.md`). A press tracker whose hold acts (a stepper's hold-repeat) can bring a selection lock for its presses, as a recognizer can.

+[chore] Internal: gestures attach for every pointer, a mouse, a pen and a finger alike (AST-094 FR43). Under a fine primary pointer an element that uses a gesture keeps one passive `pointerdown` listener (a recognizer that claims a moving finger also keeps its blocking `touchmove`, and a kept press gets its own only during a press), the page's listeners last only a press and go at a window blur, and a hovering mouse or pen reaches a hover recognizer through two passive listeners on its element. A pen's barrel button, like a right click, starts no press. A right click or a ctrl-click on macOS starts no press. A finger's or a pen's hold that does something keeps text unselected under any primary pointer, a touchscreen laptop's included, while a mouse keeps its released behavior (FR41). A mouse or pen drag that a recognizer claims takes no text selection from then on, anywhere on the page, and a finger is read once where the browser sends Touch Events without exposing `ontouchstart`. A press tracker takes a mouse press as a press, painting at once with no scroll brake. The screen-edge pan is a finger's only: it stays off under a mouse, a trackpad and a pen, and takes no `allowedPointerTypes`, and `perEventPointer` is accepted and does nothing.

A recognizer that must claim a touch mid-gesture still needs the touch to reach its element. Each event type's listener is passive unless a subscriber cancels it (the gesture host's `touchend` and `contextmenu` while a claiming recognizer or press tracker is attached, the page hold's `touchmove` while it holds, and the click guard's `click` once it first arms), so a page of pressables registers no listener that can hold a scroll.
