 - Hotfix path: if prod is on fire and waiting through `dev` is unacceptable, open the fix PR directly against `main`, merge (CI deploys automatically), then immediately fast-forward `dev` from `main` (`git checkout dev && git merge --ff-only main && git push`) so the two branches don't diverge.
 - Required GitHub secrets (repo-level, not environment-scoped): `VERCEL_TOKEN`, `VERCEL_ORG_ID`, `VERCEL_PROJECT_ID`.

 - Spec changes that alter a bench's provider list require a worker image rebuild to show up on the site (the worker bakes its OCB checkout at build time).
