- Add A22_IMAGE_ORIGIN to the pinned frame directories, so a same-host
redirect from www.autobrennero.it/WebCamImg/ cannot leave that directory,
as for the other directory-pinned packs.
- Give Autostrada del Brennero a 3-minute ambient refresh in cctvLod.js,
like the other highway packs, instead of the 5-minute default.
- DATA_SOURCES: the Open Data Hub now tags every A22 record CC0; note that
this is the aggregator's metadata, not Autobrennero's own terms.
- Tests for the redirect pin and the refresh cadence.
