Build a complete Shopify instant search and visual merchandising application in Node.js (Fastify) and React.

REQUIREMENTS & DATA MODEL:
1. Catalog Ingestion & Sync Pipeline:
   - Listen to Shopify webhooks (`products/create`, `products/update`, `products/delete`, `inventory_levels/update`).
   - Store raw catalog data in PostgreSQL (Tables: `stores`, `products`, `variants`, `collections`, `merchandising_rules`).
   - Sync structured product JSON to an embedded Typesense cluster for full-text search and vector hybrid search (using OpenAI text-embedding-3-small).
   - Index fields: title, description, vendor, product_type, tags, options (color, size), variants (sku, price, inventory_quantity, barcode), published_at, handle, image_url.

2. Search Engine & Auto-Suggest Core (API Engine):
   - Expose a public `/api/v1/search` endpoint optimized for sub-50ms execution.
   - Support query parameters: `q`, `store_id`, `filter_by` (price range, vendor, tags, variant options), `sort_by` (relevance, price_asc, price_desc, created_at, inventory_desc), `page`, `per_page`.
   - Implement automatic typo tolerance, prefix matching for instant autocomplete, and exact match SKU overrides.
   - Implement synonym expansion via a merchant configurable lookup table (`synonyms` table).

3. Merchandising Rule Engine:
   - Evaluate rules applied on top of search queries or collection pages.
   - Rule types: PIN (force product ID X to position Y), BOOST (multiplier on vector score based on tag or vendor), BURY (push out-of-stock items to the bottom), HIDE (exclude specific tags).
   - Dynamic out-of-stock pushdown: If `inventory_quantity <= 0`, append dynamic penalty to ranking score unless merchant rule overrides.

4. Merchant Merchandising Dashboard (React App):
   - Collection Merchandiser: Drag-and-drop grid to visual pin products into target visual slots.
   - Rules Editor: Visual rule builder (`IF query CONTAINS 'shoes' THEN BOOST vendor='Nike'`).
   - Search Analytics: Dashboard showing Top Searches, Zero-Result Queries, and Conversion per query.

5. Frontend Search Widget (Vanilla JS Bundle):
   - Embeddable JS script (<25KB compressed) injected via Shopify App Proxy or Theme Extension.
   - Features: Instant dropdown widget with predictive search, query history, price filters, color swatch filters, and dynamic faceted search for collection pages.

OUT OF SCOPE:
- Conversational chat AI widgets.
- Headless Hydrogen SSR render engines.
- Multi-currency cross-border dynamic pricing translation.

FAILURE MODES TO HANDLE:
- Out-of-order webhook execution from Shopify (use product `updated_at` timestamps to reject stale sync payloads).
- Burst search traffic during flash sales (rate limit query endpoint and use aggressive edge caching via Cache-Control headers for non-personalized queries).
