Expand source library batch 2: 20 recordings, 2020-06-17 to 2020-08-23
Library grows 128 -> 148 (130 videos, 18 livestreams; coverage from
2020-06-17). Twenty new source notes with attributed blurbs and
principle links, twenty original art pieces (batch-b prompts, masters,
and 80 responsive encodings), all images individually reviewed against
the art atlas with zero regenerations.
Library page meta/social copy now derives its recording count from
sitecontent.LibraryCount instead of a stale hardcoded "108".
Validators and tests updated: LibraryCount/VideoDetailCount 148, art
gate 148/592, 9-page pagination (last page 4 cards), craving filter 35,
coverage 148/130/18 spanning 2020-06-17..2026-08-17.
