"""
Workflow runner package.

Public surface:

* ``Step``, ``WorkflowRunner`` — the in-house orchestrator.
* ``WorkflowEvent`` — structured event emitted during a run.
* ``StepResult``, ``WorkflowResult`` — return shapes.
* ``StepFailure`` — raised when ``fallback=abort`` trips.
* ``extract_content`` — tiny helper shared with other modules.
