"""Shared pytest fixtures.

`fake_slack` boots the in-process FakeSlack harness on an ephemeral port and points the Slack
adapter at it via `SLACK_API_URL`, so the real `SlackAdapter` / `slack_bolt` stack runs
end-to-end with no network, tokens, or the Slack app console. See
`coworker.testing.fake_slack` and `platform/docs/FAKE-SLACK-SPEC.md`.
