Image Studio — deep engine host (E4b)

Image

The shipped Image Studio now hosts the shared media engine inside Generate — compose the AI prompt, refine it with history, then generate. Accent #7c3aed marks the mounted engine. Light app theme · clickable. No caching — refresh for latest.

What changed in E4b. Generate now mounts the shared media engine: preview the AI-composed generation prompt + its prompt guide, chat-refine it with full turn history (revert any turn), and generate straight from the composed/refined prompt. The bare prompt textarea is demoted to a seed in Brief. The standalone model picker is replaced by the engine's ProviderModelPicker (Higgsfield · google-flow). The studio's shadcn chrome stays the same — the engine is a distinct surface hosted inside it.

The seam. These pages show studio shadcn chrome (cards, stepper, segmented controls) hosting the gua-* engine panel — one shared media engine, deep-hosted by the Image Studio. Start at Generate (deep) for the full flow.
