+HyperFrames now renders scene-local video timing correctly across sequential nested templates
+and removes vulnerable runtime dependency paths. Studio also gains exact bulk easing for
+merged keyframes, atomic keyframe-cache refreshes, and smoother optimistic ease-mode changes.

+## Features
+
+- **Studio:** Bulk-edit easing for merged keyframes ([10d45def0](https://github.com/heygen-com/hyperframes/commit/10d45def058248d0d59d1448beef6a6ee91ddeba))
