version: "1.0.0" name: ceres-uitoolkit description: Design, implement, preview, automate, or diagnose Ceres runtime UI Toolkit surfaces, Ceres Neutral controls, typed bindings, and preview sessions.

Ceres UI Toolkit

Use production UI assets and bindings as the source of truth. Preview must mount the same UXML, USS, PanelSettings, scale policy, and binding path as runtime; an Editor-styled substitute is not an acceptable fidelity check.

• Read theme-and-controls.md when styling Ceres Neutral or choosing button, toggle, slider, field, scrollbar, density, and touch behavior.
• Read typed-binding.md when using the query generator, binding events, synchronizing values, or managing view lifetime.
• Read preview-and-automation.md when adding a provider or fixture, automating previews, comparing runtime snapshots, or diagnosing preview/runtime differences.

Keep runtime controls in Ceres.UIElements and preview infrastructure in Ceres.UIElements.Editor. Feature packages own composition, business state, safe areas, and product layout. Map business actions explicitly with typed C#; never infer commands from element names.
