The controller sends a wheel tick as a MouseEvent whose type bits are MOUSE_TYPE_WHEEL (src/common.rs) with the scroll delta in y, but InputService only handles the legacy WHEEL_DOWN/WHEEL_UP masks (523331/963) that current controllers never send. As a result the mouse wheel does nothing on every Android controlled device. Handle MOUSE_TYPE_WHEEL with the same stroke emulation the legacy masks use, as a purely additive branch: a 90px vertical stroke (MOUSE_WHEEL_STEP, three quarters of the legacy WHEEL_STEP - the full 120px felt too far per tick to reviewers on real devices) over WHEEL_DURATION at the current cursor position, with the same top-edge guard and queue consumption, mapped with the controller's sign convention (y < 0 = wheel down; y == 0, a horizontal tick, is ignored). The branch is gated to API 24+ like the rest of the gesture path - below that, legacy devices take the Shizuku backend or a no-op, not this class. The legacy WHEEL_DOWN/WHEEL_UP implementations are untouched. Community reports matching this gap on modern devices: #9321 (Pixel 8, Android 14) and #1466 (Android tablet).
