+"""Verify that inline <script> blocks in admin templates parse as valid JS.
+
+We had a regression where an Italian translation containing an apostrophe
+(e.g. "Errore nell'eliminazione") broke a single-quoted JS string literal,
+killing every Alpine binding on the page (the "Nuova Stazione" button no
+longer triggered openCreateModal).
+
+Strategy: render each admin page through the Flask test client, extract every
+inline <script> body and feed it to `node --check` for a syntax verdict. We
+force the IT locale so the worst-case translations (which contain apostrophes)
+are the ones evaluated.
+
+The test is skipped if `node` is not on PATH; CI images that exclude Node
+get a soft skip rather than a false failure.
