+[fix] `astryxStylex` resolves `defineConsts` values read from another file. 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. Where the primary pointer is fine, the host attaches nothing and registers no listener, following the pointer when it changes; a recognizer that reads each event's pointer itself opts out with `perEventPointer`, and a press tracker with it paints a finger's press feedback only, with no control event and no mouse or pen press. A press tracker whose hold acts (a stepper's hold-repeat) can bring a selection lock for its presses, as a recognizer can. Internal, for the touch components that adopt them; not exported from the package entry point.

+[fix] The touch press feedback and the gesture recognizers now hear page-wide input through one shared stream on the window's capture phase, so an app's window-capture `stopPropagation`, or a document-capture `stopImmediatePropagation` registered before Core, no longer hides a touch from them. 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.
