## MODIFIED Requirements

### Requirement: Streaming AI response

The assistant SHALL reply with a real AI response streamed from the backend API, using the full conversation history as context. Tokens appear incrementally as they arrive.

#### Scenario: Bot replies with streamed AI response

- **WHEN** the user sends any message
- **THEN** the assistant message appears and grows token by token as the stream delivers text

#### Scenario: Full history sent with each request

- **WHEN** the user sends a message after prior exchanges
- **THEN** all previous user and assistant messages are included in the API request so the AI has conversational context

## ADDED Requirements

The chat page SHALL provide a button to clear the current conversation and start a new one.

#### Scenario: User starts a new chat

- **WHEN** the user clicks the "New Chat" button
- **THEN** all messages are cleared and the empty state is shown

#### Scenario: New chat button disabled during streaming

- **WHEN** the assistant is currently streaming a response
- **THEN** the "New Chat" button is disabled
