What does re-importing a product do?	will importing again create duplicates re-import from the global catalogue import the same sheet twice	catalogue	src/api/catalogue.ts, services/catalogueService.go

Re-importing updates the products you already have rather than adding second copies of them. The match is made on the catalogue's own stable key, not on the product name, so a renamed product is still recognised as the same one.

What it does not do is change your prices. The global catalogue carries a typical price range rather than a price; the price a customer pays is yours and is set in your own catalogue, so an import never overwrites it.
