The `translate-ar` script is already configured. It will: 1. Fetch all products from Sanity 2. Find ones missing `description_ar` or `longDescription_ar` 3. Use the Claude CLI to translate each one 4. Write the translations back to Sanity This will **write Arabic translations directly to Sanity** (a live data change). Shall I run `npm run translate-ar` now?
