+### 0. Architectural Strategy (Strict)
+**❌ Do NOT create a package for every component.**
+**✅ Group by Dependency Weight:**
+1.  **Atoms (@object-ui/components):** Shadcn Primitives. Zero heavy 3rd-party deps.
+2.  **Fields (@object-ui/fields):** Standard Inputs.
+3.  **Layouts (@object-ui/layout):** Page Skeletons.
+4.  **Plugins (@object-ui/plugin-*):** Heavy Widgets (>50KB) or specialized libraries (Maps, Editors, Charts).
 4. The JSON Protocol Specification (The "DNA")
 You must enforce a strict JSON structure. Every node in the UI tree follows this shape:
 // @object-ui/types
