Fetch slots, match by key:

- categories > duplicatable
- special-sale-banner > one banner
- two-banner-row → two slot
- three-banner-row → three slot

Use slot.images (all of them if kind=list, first if kind=single).
url → <img src>. linkUrl → wrap in <a>. Empty or fail → keep current placeholder.
Use slot.aspectRatio from the API. Do not invent upload APIs.
