Operator found the Orion SVS 30957 flythrough merely good and asked for a more
dramatic nebula. Replaces the cosmos-scale primary with STScI's "Exploring the
Cosmic Cliffs in 3D" (Carina Nebula, Webb NIRCam — NASA SVS 31348), sourced from
its 4K master (Clifs-3d-STScI.mp4, 3840x2160) via the content pipeline:
trim 10-34s (clears the title card ~8s and end-credit card ~102s) + crossfade-loop
-> 4K master + supersampled 1080p base (5.5 Mbps, crisper than the old 2.9 Mbps
1080p-native Orion encode).
- build_pool_manifest META: cosmos -> SVS 31348 Cosmic Cliffs, new CCBY_WEBB
credit (NASA, ESA, CSA, STScI). Labels retuned for the Carina framing
(emission nebula / protostar; redshift -> distance ~7,500 ly).
- Regenerated manifest.json (also corrects stale JPL-Orion provenance left when
129bb23 updated META but not the manifest) + all ring-edge transitions from the
new base (cosmos-orbit / abyss-cosmos now zoom from the Cosmic Cliffs).
- docs/content-candidate-pool.md: record the swap + history.
269 passed, 2 skipped. New base verified text-free + full-frame by-eye across the
loop; final look to be confirmed by the operator (no Chrome on the box).
