## Purpose

Define the project identity, core value, and non-negotiable constraints for Chat Agent WebApp.
## Requirements
### Requirement: Project identity

The project spec SHALL contain the project name, a description paragraph, and a core value statement that communicates the project's dual purpose: working AI chat interface and Blazor learning journey.

#### Scenario: Project description present

- **WHEN** an AI agent or developer reads the project spec
- **THEN** they find the project name ("Chat Agent WebApp"), a description of what the app does, and the core value statement

### Requirement: Project constraints

The project spec SHALL enumerate all non-negotiable constraints that govern technical decisions across the project.

#### Scenario: Constraints enumerated

- **WHEN** a decision is made about technology, architecture, or approach
- **THEN** the project spec provides the authoritative list of constraints to check against:
  - Tech stack: .NET / C# / Blazor WebAssembly
  - LLM provider: OpenAI GPT API
  - Storage: JSON files on local disk
  - Architecture: WASM client + backend API (API key stays server-side)
  - Code style: Every Blazor concept introduced MUST have inline comments explaining what it does and why
