tests/factories.py holds image_row/make_image/make_image_async/make_tag. The 17 byte-identical _img/_tag helpers (15 modules) now import them under their old names, so no call site changed. frontend/test/support/stubFetch.js replaces 15 copies that differed only in formatting. Copies whose bodies differ (other defaults, other columns, a url-only stub) are left as they are; folding those needs a look at each caller.
