+Media Use no longer crashes when a HeyGen credentials path is a folder. Video length and size now come from one place in the core runtime.

+## Fixes

+- **Media Use:** A credentials folder means no HeyGen credential, not a crash ([32d2bc6fe030](https://github.com/heygen-com/hyperframes/commit/32d2bc6fe03007c7c8417268522516e3db7a2e87), [#4995](https://github.com/heygen-com/hyperframes/pull/4995)).
+- **Media Use:** Skip a .env folder when loading HeyGen credentials ([5f3191bdc593](https://github.com/heygen-com/hyperframes/commit/5f3191bdc59312b6d6cba231e50207919e22b7cf), [#4988](https://github.com/heygen-com/hyperframes/pull/4988)).
