"""mkdocs shim for mike compatibility.

mike parses mkdocs.yml (valid YAML stub) for its Python internals, then calls
`mkdocs build --config-file <mike-injected-temp.yml>` as a subprocess.

This shim intercepts that subprocess call, ignores the temp config, and
delegates the actual build to `zensical build -f zensical.toml` instead.
