SpatialUI Design-Style Skill — Hard Constraints for Compose UI

This skill is the code-admission ruleset for any PICO spatial application that emits Compose UI. It is intentionally short. Detailed guidance is split into references/; read on demand.

Routing boundary: this skill is a mandatory sub-contract whenever Compose UI is emitted or edited. It should be loaded by spatial-design-to-app, spatial-app-onboarding, screenshot/Figma codegen, or manual UI-edit flows before writing UI code. It is not the primary route for app generation, scaffold creation, design-package production, container/window-model decisions, or 3D scene planning.

These rules are absolute. They override personal preference, library shortcut, and generic Compose / Material habits.
