load_inventory_channels() selected entries via 'youtube_mosaic' in entry
(key presence). save_inventory() always writes a youtube_mosaic column
that the SQL round-trip materializes as an empty dict {} on EVERY entry,
so the filter matched all 18,647 inventory entries and emitted ~18.6k
inline <img> links on a single line. That produced a 4MB v2-docs/index.md
(and 2.9MB docs/index.md), hanging both V1 and V2 index pages in the
browser. A prior revert masked it; the next SQL-backed sync re-broke it.
Fix: only treat an entry as a mosaic channel when youtube_mosaic is a
non-empty dict with a logo image (136 curated channels). Regenerated both
index files via reorganize_mosaic — docs/index.md is now byte-identical
to the last known-good state (52KB); v2-docs/index.md back to 41KB.
