 ## ✨ Features
 
 ### 📦 Inventory Management
+- **Export inventory** — Download the full inventory as a UTF-8 CSV (Excel-compatible) or open a print-ready page to save as PDF; export button always visible in the inventory page header
 - **Barcode scanning** — Scan products with your phone camera using QuaggaJS; last 20 scanned products saved as tappable chips so you can re-select them without rescanning
 - **AI identification** — Take a photo and let Google Gemini identify the product, with suggestions from your existing inventory; gracefully shows a friendly message when AI quota is exhausted instead of a raw API error
 - **Smart locations** — Track items across Pantry, Fridge, Freezer, and custom locations
