In `@packages/lynx-react/src/components/ScaleFeedback/ScaleFeedback.tsx`:
- Line 12: Update the public ScaleFeedback component to use React.forwardRef,
accept the consumer ref, and pass only non-null refs to the native view element
while preserving the separate "main-thread:ref" ref used by useScaleFeedback.
In `@packages/lynx-react/src/hooks/useScaleFeedback.ts`:
- Line 80: Update useScaleFeedback so its animation keyframes preserve the
target’s original transform: capture the computed/default transform, combine it
with the scale-down keyframe, and use that stored transform instead of scale(1)
in the final keyframes of handleTouchEnd and handleTouchCancel. Add regression
tests covering existing transforms across touchstart, touchend, and touchcancel.
- Around line 145-170: Update handleTouchStart to always call
readScaleFeedbackScale(targetRef.current) at touch start, replacing the cached
scale when the measurement is valid before updating scaleRef.current and
invoking runScaleFeedback. Preserve the existing null behavior so 0x0 layouts
remain eligible for later remeasurement.

- Line 2: Update the `page` selector in the scale-feedback stylesheet to add a
Stylelint-specific suppression or configure the relevant Stylelint rule to
recognize Lynx intrinsic elements, while preserving the intentional selector and
allowing the lint check to pass.
