OBS / Streamlabs Program Source URL

Best for your `deepbeat_oj` test: add this as one full-screen Browser Source, then stream that OBS scene to your Twitch channel. The program player is muted by default so it autoplay-starts reliably in OBS; add source audio separately in OBS if needed.

Transparent Captions-Only Overlay URL

Advanced setup: use the source stream as a separate video layer, then place this transparent caption overlay above it.
