Redundancy check: find the scent twins you paid for twice

Most shelves quietly contain the same scent twice. Two perfumes can share 80% of their note pyramid while looking completely different on paper — a woody-amber designer, a middle-eastern clone, an Indian daily wearer — and you end up with three bottles that smell like one perfume. The redundancy check compares every perfume in your collection against every other, using the same DNA-style note-overlap scoring that powers the rest of FragranVerse: top, heart and base note pyramids are matched against our catalog of 8,280+ perfumes, and pairs above the similarity threshold are flagged as redundant.

It works on your own shelf, not just the catalog — add bottles you own (or check a candidate against them) and the overlap is scored instantly. The verdict separates "true twins" (same DNA, safe to own once) from "same family, different scent" (worth keeping both).
