 To prevent "div wrapper" abuse and maintain architectural integrity, we enforce a strict boundary between **Primitives** and **Semantic UI**.
 
-### 1. Primitives (Forbidden in Components)
-- **Primitives**: `Box`, `Surface`, `Stack`, `Grid` (in `ui/primitives/`)
-- **Internal only**: These should NEVER be imported by `components/`. They are for building semantic UI elements.
-- **Full flexibility**: They allow arbitrary styling (bg, border, shadow, etc.) to build semantic components.

 - **Layout Components**: `Layout`, `Container` (in `ui/`).
 - **Restricted flexibility**: Semantic components are restricted to their defined props. They do NOT allow arbitrary styling props (bg, border, etc.).

-### Primitives
-
-The primitives in [`apps/website/ui/primitives`](apps/website/ui/primitives) exist to build consistent semantics. They should not encode a “theme” directly; they expose minimal layout/styling mechanics.
-
-Examples in code today:
-
-- [`Box`](apps/website/ui/primitives/Box.tsx:1)
-- [`Stack`](apps/website/ui/primitives/Stack.tsx:1)
-- [`Surface`](apps/website/ui/primitives/Surface.tsx:1)
-
-Conceptually, primitives should either:
-
-- map typed props to standard CSS properties (style object), or
-- map typed props to CSS variables that are already in the theme contract.
-
-What primitives should **not** do: generate Tailwind class strings as their main behavior.
