Two grocery offers can look alike without being the same product. We are making match quality explicit.

• ✅ Exact matches. Same product identity, brand, variety, and pack evidence.
• ≈ Similar matches. Useful alternatives that differ in a stated way.
• 🔍 Visible evidence. See why products were grouped.
• 🛡️ No silent substitution. Uncertain matches will not appear as exact.

This foundation will support trustworthy favourites, lists, receipt analysis, and camera recognition.
