+question: What does re-importing a product do?
+also:
+  - will importing again create duplicates
+  - re-import from the global catalogue
+  - import the same sheet twice
+area: catalogue
+source: 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.
