📝 Walkthrough

Walkthrough

Docker Hub and GitHub Container Registry login steps were repositioned in CI, preview, and release workflows to run sequentially rather than inside parallel blocks. Authentication actions, versions, and credential sources remain unchanged.

Poem

I’m a bunny with badges, hopping in line,
Docker then GHCR, sequentially fine.
The tokens stay secret, the actions stay true,
Parallel blocks now let logins pass through.
Hop hop, the workflow is tidy and new!
