local-live.sh generates a sliding-window demuxed CMAF/fMP4 live stream with
ffmpeg's HLS muxer (master + EXT-X-MEDIA audio group + fMP4 init/segments) to a
temp dir, served with CORS and no caching — a no-creds local live source for the
SPF engine and the hls.js/native sandbox pages. Documents the no-cache
requirement (a positive max-age on a live playlist freezes the client's window —
a server misconfiguration, not a player bug).

apps/sandbox/scripts/live/ — spin up an ephemeral Mux live source for
exercising the live path in any HLS-capable sandbox page:
- create-stream.sh: create a low-latency Mux live stream (creds via
--token-id/--token-secret flags or MUX_TOKEN_ID/MUX_TOKEN_SECRET env;
--quiet for scripting)
- broadcast.sh: push an ffmpeg testsrc + tone feed to the stream
- dvr-url.sh: resolve active_asset_id to the DVR/EVENT playback URL
- live-test.sh: orchestrate create -> broadcast -> wait -> open the page,
parameterized by --page (renderer-agnostic), --flavor sliding|dvr|both,
--port, --params, --latency; deletes the stream on exit unless --keep
- README.md: quick-start, manual steps, and cross-renderer reuse notes
Credentials are read only from flags/env; none are committed.
