+- **Generated Files**: Located in `src/lib/api/generated/` with separate directories for endpoints and schemas
+- **Enhanced Client**: Custom axios client with retry logic, loading states, and comprehensive error handling
+- **Configuration**: `orval.config.ts` defines generation settings and mutator overrides
+- **Source**: Auto-generated from `http://localhost:8000/openapi.json`

 ## Development Notes
 
 ### Environment Variables
 Required in `.env.local`:
-- `NEXT_PUBLIC_API_URL` - Backend API URL
+- `NEXT_PUBLIC_API_URL` - Backend API URL (e.g., `http://localhost:8000/api`)
 - `NEXT_PUBLIC_ENV` - Environment (development/production)
 - `NEXT_PUBLIC_TELEMETRY_ENDPOINT` - OpenTelemetry endpoint
 
 ### Bun Configuration
-- Uses `bunfig.toml` for configuration
-- Registry set to `https://registry.npmmirror.com` (Chinese mirror)
-- Network access allowed for scripts
+- **Registry**: Uses Chinese npm mirror (`https://registry.npmmirror.com`)
+- **Network Access**: Allows scripts to access network resources
+- **Configuration**: `bunfig.toml` contains Bun-specific settings
 
-### Code Generation
-- Run `bun run generate:api` after backend API changes
-- Uses Orval to generate React Query hooks and TypeScript types
-- Automatically formats output with Prettier
+### Static Export Configuration
+- **Output Mode**: Configured for static export (`output: 'export'`)
+- **SPA Mode**: Trailing slash enabled for SPA routing
+- **Image Optimization**: Disabled for static export compatibility
+- **Deployment**: Outputs to `out/` directory for static hosting
 
-### Styling
-- Primary styling with Tailwind CSS
-- Less for complex styles in `src/styles/less/main.less`
-- Apple design system with custom colors and components
-- Dark/light theme support with smooth transitions
+### Code Generation Workflow
+1. Backend API changes trigger OpenAPI spec updates
+2. Run `bun run generate:api` to regenerate client code
+3. Orval processes OpenAPI spec and generates:
+   - React Query hooks for all endpoints
+   - TypeScript schemas for request/response types
+   - Enhanced client integration with custom axios instance
+4. Prettier automatically formats generated code
 
-### Testing
-- Currently no test framework configured
-- ESLint for code quality
-- TypeScript for type safety
