15- Builds into its own `Edit` scene (`--scene`), so 3D scenes stay untouched. Clips go on alternating channels 1/2, crossfades (`CROSS`) on 3, the title on 4, clip audio on 6/7 (movies get their sound strip), and music on 8 (trimmed to the edit with a `--audio-fade` volume fade-out).
16- A clip may be a movie, a still (`--still-seconds`), a folder of frames, or a `####` pattern. Each crossfade overlaps the previous clip by `--crossfade` frames, so the edit gets shorter by that much per cut. Re-running replaces the previous edit.
17- Sets **view transform Standard**: footage must pass through untouched (measured: AgX turned pure red into 0.86/0.23/0.13). Grade on purpose with strip modifiers instead.
