Add keyframe support for transform, opacity, and volume properties. Includes animation engine (interpolation, mutations, resolvers), timeline markers with selection/snapping, properties panel toggles, keyframe-aware renderer, and full undo/redo command support. Also refactor element command constructors to object params, extract timeline pixel math to pixel-utils.ts, and update cursor rules. |
