A carousel is an ordered set of single-image slides — each slide is now the deep host of the shared media engine. Per slide: its own composed-prompt panel, its own provider/model, its own refine history. No per-resource checklist — slides are flat images. Compose the slide, generate, pick one.

[NEW] The shared media engine, hosted per-slide: a Higgsfield-only ProviderModelPicker, an editable composed image prompt + guide, a refine row with revertible history, and a slide-scope badge. This replaces the old per-slide prompt Textarea and the old single whole-carousel model Select — each slide owns its own provider/model (per-slide override) and its own refine history; the panel remounts per slide. The composed/refined prompt pins to this slide's snapshot so Generate runs exactly it.

On-platform slide-image generation is Higgsfield-only — google-flow stays in the manual / DIY path.

This slide carries its own model — change it without touching the other slides. There is no longer one model for the whole carousel.

Prompt guide
1.Write a vivid, brand-aware description for this one slide — scene, mood, light, palette and the exact product — as if briefing a photographer.
2.Keep ample negative space for copy: the card headline & link live on the ad, not baked into the image.
3.Hold the carousel's look consistent slide-to-slide — same palette, grade and 4:5 framing across Hook → CTA.
Prompt composed by your AI provider; the slide image is delivered by your Higgsfield connector. Pinned to slide 1's snapshot.

This refine history is this slide's own — slide 2 keeps a separate one (the panel remounts per slide). Compose & refine use the free text path (your AI key / platform key) — never a media credit. Generate below spends a media credit and runs the prompt pinned to slide 1's snapshot.

Generating spends a media credit and resolves your Higgsfield connector via resolveMediaProviderKey. Picking, uploading and Save to library are free — and only compose / refine uses the platform text key.
Card headline & link? Those live on the ad, not on the slide image. Set them after delivery — this studio produces the slide image only.
Slide 1 has an image · finish slides 2 & 4, then deliver the carousel to the ad.
