"""Runs the plain-node vision panel zoom test (tests/js/test_vision_zoom.js).

Same thin pytest wrapper pattern as test_vision_rows_js.py: shells out to
``node`` and asserts the script's own exit code. Skips (does not fail) when
node is not installed.

Covers gitea:Adriano/TieMeasureFlow#115 #122 (dal #122 il test JS verifica che lo zoom non sia piu' nel componente).
