justice-bac ships a one-command Fly.io deploy for Mike

justice-bac built out the full deployment story Mike has been missing: containers for the backend and the web front-end, health checks, region pinning, and machines that auto-stop when idle. All of it targets Fly.io, a developer-friendly host that runs apps close to users in regions worldwide.

The centrepiece is a long, interactive deploy script that handles the awkward parts - discovering secrets from local config or prompting for them, auto-generating signing keys, deriving public URLs from app names, and retrying when Fly's remote builder gets flaky. A companion GitHub Actions workflow lists every secret the deploy needs by name, which doubles as a useful checklist for anyone porting this. A small but smart fix lets the frontend build cleanly even when its Supabase keys aren't present yet.
