TL;DR


We're going to build a hybrid live stack: presenters connect over WebRTC for sub-second feedback, the SFU re-publishes to RTMP, and the audience plays it back over LL-HLS at ~2 seconds. By the end you'll have a decision tree, a working ingest config, an LL-HLS player setup, and a list of the failure modes that bit me in production.
