HEF — new altitude ☁️ sky  (“up in the clouds, flying over the earth”) — sits between orbit and coast

Selected = the clips you chose; these get downloaded → processed → wired into the sky pool (planned per-clip processing in green). Candidates = the only thing still open — longer versions of the three rainforest moods you liked but found too short.

Everything streams straight from the source (nothing downloaded yet): press play on a card. Each clip auto-seeks to its suggested clean window (N–Ms). Audio is muted — judge the footage only.

✅ Selected — going into the sky pool (15) — sourcing closed

Previews stream the raw source; the green note is what we'll do to each before baking the looped 1080p pool clip. CC-BY clips carry the required credit.

🆕 Candidates — sourcing closed

All 15 clips chosen (aircraft 4 · rainforest 4 · coast 3 · mountains 4). The full candidate history — every reviewed clip, what was picked or dropped, and the rejected sources — lives in docs/content-candidate-pool.md. Next step is the processing pass + wiring the sky scale into the ring between orbit and coast.
