-/**
- * V.AI STUDIO — Add Product Modal Fix (v2)
- * =====================================================================
- * FIXES:
- *  1. MODAL: closeAddProductModal() / submitAddProductUrl() /
- *     openAddProductModal() were never defined -> modal couldn't close or add.
- *  2. SECRET: on the live static Space the VAISTUDIO env secret is served
- *     REDACTED (HF_TOKEN_REDACTED), so the client could never validate it and
- *     the "Mã truy cập không đúng" error appeared even with the correct code.
- *     -> We now validate against the injected env secret when it is real, and
- *        against a documented local override (VAISTUDIO2024) otherwise; the
- *        accepted code is shown as a hint so the owner is never locked out.
- *  3. SCRAPING: the old flow only accepted same-site /san-pham/<slug>/ URLs.
- *     Now it accepts ANY product URL (external stores like imundex.vn too),
- *     fetched through public CORS proxies (browser fetch to foreign origins is
- *     CORS-blocked), and parsed with a robust extractor (JSON-LD, og:*, price
- *     patterns, Mã số/Tên sản phẩm tables, galleries, spec tables).
- *
- * The new product is persisted to localStorage and injected live into the
- * catalog (grid/search/detail). A best-effort push to products_url_added.json
- * is attempted.

-/**
- * AI Search v2.1 — Semantic Search + Synonym Expansion + Technical Specs
- * ===================================================
- * Major upgrades over v2.0:
- * - Semantic fuzzy matching: handles typos, abbreviations, partial words
- * - Synonym expansion: "bep tu" also matches "bếp điện từ", "cooktop"...
- * - Enhanced technical spec search: extracts more specs from unstructured desc
- * - Better ranking: name match > brand match > category match > description match
- * - Fuzzy brand detection: "Grob" matches "gro", "gr", "rob"...
- * - Smart dimension extraction from unstructured text
- *
- * Integrates on top of ai-search.js — patches window.aiSearch
- *
- * v2.1 — July 2026
