 When using Docker buildx with registry-based cache (cache-from/cache-to type=registry), the Docker Hub login step must run on ALL builds, not just main branch. Without login, PR builds fail on second run with 'push access denied, repository does not exist or may require authorization' when trying to write cache layers.
