Render — "stuck in Queued" fix:
- Jobs were created Queued and only a Windows AE node could claim them, so in the
dev stack (no node) they queued forever.
- New devworker package: in-process mock worker drives Queued jobs through the steps
with progress + live preview frames → Done. Enabled via RENDER_DEV_WORKER (default
true in compose; set false in prod where real nodes claim jobs).
- db: DevClaimNextQueued (atomic oldest-queued → Preparing) + UpdateJobStepProgress
- Verified live: a stuck job advanced Preparing→Done in ~10s with frontend polling.
Studio — predefined template structure:
- Projects are always copied from a template; structure is fixed. Users customise
existing layers, they don't add new ones.
- New studio-config flag ALLOW_ADD_LAYERS (false): StudioToolbar (add text/image/
video/shape) returns null; SceneEditSidebar "add text layer" button hidden.
