A bundle of quality fixes and small refinements. The manuscript editor persists its layout to the proper relational home now (instead of stuffing it into the production JSON blob), and the Generate-structure action survives leaving the Manuscript tab mid-run. YouTube project pages now share the film project page again (a previous repoint got reverted). Document imports gained body-size caps, rate limits on the classify pass, and a zero-scene guard. The NLE went through an audit round two with null-clears, scene-panel isolation, free-audio guards, and a Menu description fold. And a canonical SlideOverRail atom now backs the NLE inspector, the Artifacts tray, and the new Publish rail so they read as one system.
