-- RENDER SCHEMA — scene snapshot jobs
-- Async "render one frame per scene from After Effects" jobs. A node claims a
-- queued snapshot, runs aerender for the scene's comp at a single frame, uploads
-- the still to object storage, and posts back the image URL. render-svc then
-- writes it onto content.scenes.snapshot_url (same DB, cross-schema) so the
-- studio scene bar + admin show a real thumbnail.
