"""
Robust shim for project configuration.

This file attempts to locate a real configuration module named either
- a package module at `config/config.py` (importable as `config.config`), or
- a standalone `config.py` file elsewhere on `sys.path`.

It then imports that module and re-exports its public names so existing
`import config` usages continue to work regardless of whether the
configuration was moved into a `config/` directory or left as a file.
