// TestMain isolates the cli test suite from the developer's real
// ~/.config/lectio. Several reference/random tests assume English book
// abbreviations (e.g. "Jn 3:16"); a user config with ui_language = pl makes
// sigla_style = auto resolve to the Polish dialect, where "Jn" is not a valid
// abbreviation, so those tests fail on such a developer's machine even though
// they pass on a clean CI. Pointing LECTIO_CONFIG at a throwaway,
// non-existent path forces the built-in defaults for every cli test and keeps
// the suite from ever reading -- or writing -- the real user config.
