 ## UI Rules
 
 - Prefer shadcn/Base UI components over custom implementations. Add them with `pnpm ui:add <component>` from the repo root.
+- The Pro `@reui` registry is configured in `packages/ui/components.json`; add items with `pnpm ui:add @reui/<name>` and answer `n` to every overwrite prompt so local component customizations survive. It reads `REUI_LICENSE_KEY` from the environment — agents get it from their Multica agent environment, humans export it in their own shell. Never write the key into a repo file.
+- ReUI ships source, not a dependency: route the vendored output to our layout (new primitives to `packages/ui/components/ui/`, compositions to `packages/views/<domain>/`) and rewrite it to our conventions before committing.
 - Use design tokens and semantic classes; avoid hardcoded colors.
 - Do not introduce extra local state unless the design requires it.
 - Handle overflow, long text, scrolling, alignment, and spacing deliberately.
