"""Shared fixtures for gateway tests.

The ``_ensure_telegram_mock`` helper guarantees that a minimal mock of
the ``telegram`` package is registered in :data:`sys.modules` **before**
any test file triggers ``from gateway.platforms.telegram import ...``.

Without this, ``pytest-xdist`` workers that happen to collect
``test_telegram_caption_merge.py`` (bare top-level import, no per-file
mock) first will cache ``ChatType = None`` from the production
ImportError fallback, causing 30+ downstream test failures wherever
``ChatType.GROUP`` / ``ChatType.SUPERGROUP`` is accessed.

Individual test files may still call their own ``_ensure_telegram_mock``
— it short-circuits when the mock is already present.
