Thumbnails failed immediately on any clip past ~2 min. The one-pass select
expression joined frames with a flat a+b+c+... chain, which overflows ffmpeg's
recursive expression parser past ~120 terms ("Error while parsing expression").
Join the same terms as a balanced tree (depth O(log N)) instead — identical
selection, still one decode pass, exact per-tile frames preserved.
- generate_thumbnails management command: runs synchronously and streams each
phase to stdout, so jobs are watchable without tailing app logs
- surface ffmpeg's stderr instead of swallowing it in CalledProcessError
- fly: min_machines_running = 1. Background thumbnail jobs outlive the HTTP
request that triggers them, so scale-to-zero let the proxy autostop the VM
mid-job and leave projects stuck "running"
- timeline: replace the two split playhead bars (pinned lanes vs scrolling
tracks) with one full-height overlay, positioned in JS to track horizontal
scroll and sit above the translucent header

- Project gains a clip FileField; POST /api/projects/ creates one from an
uploaded otio + clip (<=100 MB), owned by the requester
- add /api/me/ and project-detail; scene GET is public (view without login),
PUT stays owner/collaborator-only
- serve media in DEBUG (range requests for video seek); CORS for the cljs dev
origin with credentials
- seed_demo now builds the Challengers project from the bundled otio + 480p clip

A Project (owner, OTIO file, fps, scene JSON) persists the timeline. Session
API: list projects, GET/PUT scene, serve OTIO. Admin manages users/projects;
seed_demo creates a project from the bundled one_two_three.otio.
