## Overview

#### Purpose and Runtime
Code Lab is a TypeScript/React learning interface organized around selectable programming topics and interactive content. It runs as a Next.js application, with the App Router rooted at `app/layout.tsx` and `app/page.tsx`. Styling is primarily component-scoped CSS Modules plus global styles in `app/globals.css`.

#### Application Composition
`app/CodeLabApp.tsx` is the central application shell assembled by the route entry point. It coordinates the persistent layout regions—header, sidebar, and primary content—rather than exposing separate route-level pages for each topic. `app/CodeLabApp.module.css` defines shell-level presentation.

#### State and Navigation Boundary
`context/CodeLabContext.tsx` is the shared client-state boundary for the selected topic and other cross-component UI behavior. View components should consume or update this context instead of coupling sidebar selection directly to content rendering. This creates a flow from navigation interaction to centralized state to the active view.

#### Content Model
Topic content is represented as local static data in `data/topicsData.ts`; a sample automation-oriented payload also exists at `data/automation-run.json`. The data layer separates curriculum/content definitions from rendering components, allowing `TopicView` and related widgets to render topic-specific material without embedding all content in the app shell.

#### Primary UI Stages
The primary control flow is:
1. `components/Header/Header.tsx` renders persistent top-level branding or controls.
2. `components/Sidebar/Sidebar.tsx` presents topic navigation and updates shared selection state.
3. `components/HomeView/HomeView.tsx` renders the default or unselected-topic experience.
4. `components/TopicView/TopicView.tsx` renders the selected topic using local topic data.
5. `components/TopicView/InteractiveWidget.tsx` provides topic-level interactive behavior.
6. `components/CodeBlock/CodeBlock.tsx` renders code-oriented content, while `components/Toast/Toast.tsx` provides transient user feedback.

#### Interaction and Presentation Boundaries
Feature components own their styles through colocated modules, including `components/TopicView/TopicView.module.css`, `components/CodeBlock/CodeBlock.module.css`, and `components/Toast/Toast.module.css`. This keeps visual concerns local while the context remains the cross-feature coordination mechanism. No server API, database, authentication provider, or external service integration is evident from the repository tree; content appears bundled with the frontend.

#### Build Infrastructure
Next.js behavior is configured in `next.config.ts`; TypeScript compilation is governed by `tsconfig.json`. Dependencies and runtime scripts are defined by `package.json`, with npm lock resolution in `package-lock.json`. The deployable unit is therefore a single Next.js frontend application rather than a multi-service system.
