 ### Sitemap + robots.txt
 - Do NOT ship public/sitemap.xml or public/robots.txt (nginx proxies both to Meshkee API).
+- Live sitemap is an index: /sitemap.xml → /sitemap-main.xml + /sitemap-products.xml.
 - Publish GET /meshkee/sitemap-config.json generated at build time from app routes.
 - Include public static routes automatically; exclude auth/checkout/cart/admin paths.
 - Canonical detail URLs (Meshkee defaults — omit templates unless customized):
   - Product: /products/{id}/{nameFaSlug} → GET /tenants/{domain}/products/by-id/{id}
+  - Category: /products/category/{id}/{nameFaSlug} → GET /tenants/{domain}/categories/by-id/{id} (then list products with categoryId)
   - Blog: /blog/{id}/{titleSlug} → GET /tenants/{domain}/blogs/by-id/{id}
   - Portfolio: /portfolios/{id}/{titleFaSlug} → GET /tenants/{domain}/portfolios/by-id/{id}
 - Slugify: Farsi letters kept, spaces → -, strip other punctuation. Do not use legacy DB slug in public URLs.
