HyperFrames v0.8.21

Released on 2026-08-31.

Studio agents can now see the current frame, select and inspect elements, edit content, transform layouts, and author motion through WebMCP.
Preview assets refresh reliably, hidden sub-composition layers can be restored, and player failures now surface instead of stalling silently.
