The diamond context menu still declared `onChangeEase` and `onCopyProperties` props, and `TimelineOverlays` still threaded `onChangeKeyframeEase` plus a `keyframeCache` it never read. Nothing on any timeline branch calls them, so they are removed along with the `onChangeKeyframeEase` callback implementation. Also from review: - `deleteSelectedKeyframes` only falls back to the sole keyframed animation when there is exactly one. A collapsed selection key carries no animation id, so taking the first of several deleted an arbitrary tween's keyframe. - The duration-less retime test asserts the real 87.601% instead of `expect.any(Number)`, so a wrong timing basis fails it. - `Timeline` wires the keyframe handlers' `onSelectSegment` through to the diamonds; it was built and then dropped, so segment ease selection never fired. - The flat text section arms auto-focus in state rather than reading and clearing a ref during render, which Strict Mode's double render swallowed.
