Git¶
User-level git config plus the security-key signing workflow, git-town aliases for parallel branch development, host-specific auth strategies, and a slot for private overlays.

| Page | Purpose |
|---|---|
| Git config | .config/git/config — the canonical user-level config. |
| git-town | Branch-chain workflow aliased directly under git. |
| Authentication | Per-host auth strategy (GitHub OAuth, GCM for Codeberg/GitLab). |
| Signing & security keys | SSH-signed commits from a YubiKey resident key. |
| Private overlay | Unconditional include at the end of .config/git/config for secrets. |
