/**
 * Handles the embedded video of a Google Motion Photo.
 *
 * A Motion Photo is a still JPEG with a short MP4 clip appended to the end of
 * the file. The `motionPhoto` facet exposes `videoSize` (the byte length of
 * that appended clip), which lets us fetch just the video with a single HTTP
 * Range request instead of downloading the whole file: `Range: bytes=<offset>-`
 * where `offset = size - videoSize`.
 *
 * The composable owns the blob lifecycle: it memoizes the object URL per
 * resource id (so hover + click don't double-fetch) and revokes every URL it
 * created when the owning scope is disposed.
