+## Key Technologies
+
+### JSON Component Factories
+```typescript
+// Pure stateless components
+export const TreeCard = createJsonComponent<TreeCardProps>(treeCardDef)
+
+// Stateful components with hooks
+export const ComponentTree = createJsonComponentWithHooks<ComponentTreeProps>(
+  componentTreeDef,
+  {
+    hooks: {
+      treeData: {
+        hookName: 'useComponentTree',
+        args: (props) => [props.components || []]
+      }
+    }
+  }
+)
+```
+
+### Hook Infrastructure
+- **95+ custom hooks** organized by domain
+- **Hook registry system** for dynamic loading
+- **Type-safe hook calls** with TypeScript
+- **Composable state management** patterns
+
+### Component Registry
+- **373 registered components**
+- **Centralized routing** through registry
+- **Metadata storage** for component properties
+- **Dynamic component resolution**
+
+### JSON Schema Support
+- **204 full JSON definitions**
+- **337 page/schema definitions**
+- **Type-safe JSON validation**
+- **Bindings and transformations** support
+
+---
+
+## Architecture Highlights
+
+### 1. Component Rendering Pipeline
+```
+User Action
+    ↓
+Page Router (pages.json)
+    ↓
+Registry Lookup (json-components-registry.json)
+    ↓
+Component Factory (createJsonComponent*)
+    ↓
+Hook Initialization (if stateful)
+    ↓
+JSON Renderer (component-renderer.tsx)
+    ↓
+React Output
+```
+
+### 2. State Management Pattern
+```
+Custom Hook (use-*.ts)
+    ↓
+Hook Registry (hooks-registry.ts)
+    ↓
+createJsonComponentWithHooks()
+    ↓
+Component State + Props
+    ↓
+JSON Bindings
+    ↓
+Rendered UI
+```
+
+### 3. Type Safety Layer
+```
+TypeScript Interface (interfaces/*.ts)
+    ↓
+Registry Type Definition
+    ↓
+Component Factory Type
+    ↓
+Hook Arguments Type
+    ↓
+JSON Data Type
+    ↓
+Props Validation
+```
+
+### 4. Configuration Management
+```
+pages.json (Routing)
+    ↓
+json-components-registry.json (Registry)
+    ↓
+src/config/pages/*.json (Schemas)
+    ↓
+Custom Hooks (State)
+    ↓
+Component Exports (json-components.ts)
+```

+```json
+{
+  "id": "tree-card-container",
+  "type": "Card",
+  "bindings": {
+    "className": {
+      "source": "isSelected",
+      "transform": "data ? 'ring-2 ring-primary' : 'hover:bg-accent/50'"

+**Export**: `src/lib/json-ui/json-components.ts`
+```typescript
+import treeCardDef from '@/components/json-definitions/tree-card.json'
+export const TreeCard = createJsonComponent<TreeCardProps>(treeCardDef)
+```
+
+### Stateful JSON Component (ComponentTree)
+**Hook**: `src/hooks/use-component-tree.ts`
+```typescript
+export function useComponentTree(components: Component[], selectedId: string | null) {
+  const [tree, setTree] = useState<TreeNode[]>([])
+  // ... complex state management
+  return { tree, expandedNodes, selectedNode }
+}
+```
+
+**Registry**: `hooks-registry.ts`
+```typescript
+export const hooksRegistry = {
+  useComponentTree: () => import('@/hooks/use-component-tree').then(m => m.useComponentTree)
+}
+```
+
+**Component**: `json-components.ts`
+```typescript
+export const ComponentTree = createJsonComponentWithHooks<ComponentTreeProps>(
+  componentTreeDef,
+  {
+    hooks: {
+      treeData: { hookName: 'useComponentTree', args: (props) => [props.components] }
+    }
