 Use `slot.key` in the placeholder. Match `pageKey` to the website page. For a single image: `images[0]?.url`. For a list: map `images` (if `itemCount` is set, that many images are expected). Each image may include `titleFa`, `titleEn`, `subtext`, and `linkUrl`. If `linkUrl` is set, wrap in `<a href={linkUrl}>`. Pick `titleFa` or `titleEn` from the site locale. If `images` is empty, keep the local fallback.

+`kind` is `single` (one image) or `list` (duplicatable). For a fixed row, set `itemCount` (e.g. `2`). Leave `itemCount` null for an unbounded slider. `aspectRatio` must look like `16:9`. Do not invent CMS/upload APIs.
