Saved 2026-09-25 19:22 by @benjaminsen (bot): Added the French-market Mars Duo 78.8 g (5000159519328), named by family/mars-bar. Identity, importer block, full French ingredient statement and allergens read from the Open Food Facts side-panel photograph (2021-10-04); per-100 g and per-bar nutrition from the 2020 panel photographs; an earlier wrapper (2019) naming Mars Chocolat France kept as an unconfirmed observation. GS1 prefix owner per the existing company stub (GS1 GDSN list). Amazon.fr only has UK-labelled 3- and 6-bar lots (unavailable), recorded as a markets gap. Maker status and country of origin are open gaps.. Current is v2.
