"""Repo-wide test config for tradein-mvp/backend.

Registers custom pytest markers so they don't emit PytestUnknownMarkWarning
when used (`--strict-markers` is not enabled in pyproject.toml, so an
unregistered marker would only warn, not fail — this just keeps output clean
and documents intent in one place). Also resets cross-test-file shared
rate-limiter state (see fixture docstring below).
