## 💡 Key Concepts

### Hooks
Reusable business logic extracted from components. Import and use in any component.

### JSON Orchestration
Define pages using JSON schemas instead of writing React code. Rapid prototyping.

### Component Registry
Maps JSON component types to actual React components. Extensible.

### Action Executor
Handles CRUD, navigation, API calls, and custom actions from JSON schemas.

### Data Source Manager
Manages KV store, API, static, and computed data sources.
