## ADDED Requirements

### Requirement: API client handles all backend endpoints
The system SHALL provide a typed HTTP client for all backend API endpoints.

#### Scenario: GET request
- **WHEN** the client calls api.get('/projects')
- **THEN** it sends a GET request to /api/v1/projects
- **AND** returns typed Project[] data
- **AND** includes the Authorization header with the current access token

#### Scenario: POST request
- **WHEN** the client calls api.post('/projects', data)
- **THEN** it sends a POST request with JSON body
- **AND** returns typed Project data

#### Scenario: Error handling
- **WHEN** a request returns 4xx or 5xx
- **THEN** the client throws an ApiError with status code and message
- **AND** the error can be caught and displayed to the user

### Requirement: API client supports request/response types
The system SHALL use TypeScript interfaces matching the backend Pydantic schemas.

#### Scenario: Type safety
- **WHEN** a developer uses the API client
- **THEN** request and response types are checked at compile time
- **AND** mismatches produce TypeScript errors
