Story: synthetic decode::VideoFrame → wisp VideoTexture → Sprite
(M-MEDIA.12 / AUT-108).
Proves the second seam — the video-side counterpart to the audio
WaveformBarRect handoff. The frame is constructed by hand
(decode crate, BGRA bytes) and uploaded to wisp’s pre-existing
VideoTexture. wisp doesn’t know where the bytes came from.
