Custom renders

From a completed playlist, open Render with full control over backgrounds: supply your own assets, pull from File Drive, or generate images/videos first in the media-generation playground. Choose background mode (image / video / mixed), track versions, optional captions (non-instrumental), then run on your render server.

• User-provided assets reuse existing Fal/S3 URLs (no browser re-upload).
• Generate backgrounds in Media Gen / Playground before attaching them to a render job.
• Customize render styles and generation engines for consistent, higher-quality output.
• Jobs appear under Renders; detail shows status, assets, and final video when ready.
• render-server performs longform composition; dispatch runs on main-server workers.
