### Sitemap + robots.txt
- Do NOT ship public/sitemap.xml or public/robots.txt (nginx proxies both to Meshkee API).
- 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}
  - 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.
- After deploy: business dashboard → Website → Settings → Sync sitemap config (optional for CMS URLs; needed for static pages).

### On-page SEO (every public page)
- Unique <title> and meta description on every crawlable page
- Exactly one H1; H2/H3 for real sections
- All content images must have meaningful alt (CMS title when available)
- Prefer CMS fields for titles/descriptions; never leave Next defaults
