The R1/R3 residuals on this PR were fixed at the top of the stack, so they only cleared once every branch above landed. They belong here, next to the code they correct: - `idFromSelector` inverts `idSelector` for both regex readers, so the post-commit cache refresh stops skipping the CSS-unsafe ids `idSelector` exists to support. - `deduplicateKeyframes` drops `ease` when it is ambiguous; the flag was the only honest answer and the last-writer-wins curve belonged to an arbitrary colliding tween. - `isStaticPositionHold` is now the single owner of the hold skip. The `sourceAnimations` filter and the `allKeyframes` filter had diverged on whether `immediateRender` counts as a property. - The keyframe-cache setters no-op when the write changes nothing, instead of handing every subscriber a fresh Map. - `reset()` clears `focusedEaseSegment`. - The test hook `delete`s its window key rather than setting it to undefined, so feature detection still works. - The `toClipKeyframes` fixture uses `as unknown as T` with the justification CONTRIBUTING.md asks for.
