"""Tests for drill-to-anki.py default-path and deck-name helpers.

The script is a PEP 723 uv-run script that imports genanki, which uv resolves
at runtime but isn't installed in the test environment. The fixture stubs
genanki in sys.modules so the module loads; the pure helpers under test never
call into it.
