Three more pieces of the NLE fill in. A deliverables panel lets you choose the output aspect ratio from nine standard sizes, with a crop or letterbox strategy per delivery. A preview render button renders a quick preview without touching the final assemble path. And the narration endpoint that landed as a stub earlier is the real implementation now, so A1 pulls proper full-length narration. An effects panel also arrived as the first pass of the effects work. Some cleanup came along too: dead film_overlays CRUD stubs got swept out of the imperium side.
