HEF — expanded candidates, all altitudes (licenses widened: CC0 / PD / CC BY / CC BY-SA / Pexels — no NC/ND)
~10 fresh options per altitude, each chosen for a long clean window (45–60s where possible) so we can use more of the source — not trim to ~24s. Press play on a card; it seeks to the suggested window (N–Ms). Audio muted.
Pick favorites per altitude by id. Longer loops mean bigger files; the pipeline caps bitrate to keep LFS objects under ~25MB. Big-source clips are flagged ⚠.
