/**
 * The Record-motion panel's server half, minus the I/O: what `POST /api/editor/motion-video`
 * accepts and how it names things. Kept pure — no fs, no network — so it is testable the way
 * `recording-sink.ts` and `save.ts` are; `server.ts` owns the request and the job.
 *
 * The page POSTs the recording's raw bytes (a MediaRecorder Blob or a picked file) with the
 * blob's own Content-Type, and the asset options as query parameters. Raw rather than multipart
 * because the sidecar has no multipart parser beyond the recorder's frame sink, and a single
 * binary body is the simplest thing both sides get right.
