# tests/test_shelve_numbers.py
"""Unit tests for scripts/shelve_numbers.py.

soffice isn't available in the test environment, so _convert_to_xlsx is
mocked to copy a pre-built XLSX fixture into the expected output path —
everything downstream (extraction/chunking/storage) runs for real via
scripts.shelve_xlsx.run.
