+Built-in transcription now runs inside the HyperFrames desktop app. `transcribe --json` streams words as they are heard, except with parakeet-mlx. Studio drags after a resize, undo or reload land where they were pressed.

+## Features
+
+- **CLI:** Stream heard words on the transcribe --json progress stream ([156e87766](https://github.com/heygen-com/hyperframes/commit/156e87766c77c8b9c680b7dc107f94b4ee734f17), [#5127](https://github.com/heygen-com/hyperframes/pull/5127)).
+
+## Fixes
+
+- **CLI:** Read the WAV in JS so Built-in transcription runs inside Electron ([f7bba2288](https://github.com/heygen-com/hyperframes/commit/f7bba2288dfcbfbf0c93c8c63caee1893a442b9d), [#5129](https://github.com/heygen-com/hyperframes/pull/5129)).
+- **Core:** Keep nested scenes in place during a drag when the root has no timeline ([d94708e53](https://github.com/heygen-com/hyperframes/commit/d94708e5312df021e1fdcac421f00ed3015f11bd), [#5115](https://github.com/heygen-com/hyperframes/pull/5115)).
