Cross-Circuit Compatibility Wizard

1. **Smart Cross-Reference Engine**  

   - Instantly suggests **pin-compatible alternatives** for ICs, transistors, capacitors, etc. when a part is out of stock.

2. **Real-Time Stock Sync**  

   - Flags alternatives **available in your inventory**, with links to their product pages.  

   - Displays price/savings comparisons (e.g., _"Save $0.32 with this substitute"_).  

3. **Designer Mode**  

   - Engineers can input **custom parameters** (e.g., "NE555 substitute, DIP-8, ≤10mA") to find niche replacements.  

   - Export results as a BOM (Bill of Materials) CSV for project planning.  

4. **Seamless Integration**  

   - Works on product pages, cart, and search results.  

   - Compatible with WooCommerce, Shopify, Magento.
