"""Central test configuration.

Sets dummy environment variables at import time so modules that read
``os.environ`` at module load (slackio, interactions, handler) can be imported
without real AWS credentials.  Real values are monkeypatched per-test where
needed.

A default AWS region is set too: the handler/slackio modules construct
``boto3.client(...)`` at import time, which raises ``NoRegionError`` on a CI
runner with no AWS config. Client construction is offline; every real AWS call
is monkeypatched in the tests.
