+/**
+ * V.AI STUDIO - UNIVERSAL PATCH v1048
+ * Fixes all missing functionality:
+ * 1. AI Search - Implements actual search with semantic matching
+ * 2. Order/Quote buttons - Ensures all handlers work
+ * 3. Excel/PDF Export - NO LONGER OVERRIDES (handled by vai-export-*.js files)
+ * 
+ * v1048: Removed broken exportExcel/exportPDF overrides that broke export
+ *        (captured undefined before qr-payment.js loaded)
