The spike's central question — can a SurfaceView be composited behind a
transparent Tauri WebView on Android — is answered yes, verified on a physical
device. No upstream issue blocked it and none demonstrated it; this appears to
be the first working instance.
Marks DR-148 done behind the flag and records what is confirmed versus what is
still open: playback and positioning are verified, but the individual native
controls (seek, audio-track, subtitle), the mini-player transition, and the
MediaCodec hardware-decode claim are not yet each measured. The mini-player
transition is called out as the known gap, since it is the one case where the
fullscreen assumption behind "no rect plumbing needed" does not hold.
