automatically generates artwork beneath your sketches as you draw.\n\n## Features\n\n- **🎯 Canvas-Focused**: Clean, minimal interface focused purely on the drawing experience\n- **🔐 Basic Auth Protected**: Secure access with username/password authentication\n- **📏 Configurable Canvas Size**: Choose from 512x512, 768x768, or 1024x1024 pixels\n- **✨ Auto-Generation**: AI generates artwork automatically as you draw\n- **🎭 Exact Size Matching**: Canvas and AI output are exactly the same dimensions\n- **🔄 Toggle Views**: Switch between sketch overlay and pure AI artwork\n- **💾 Direct Save**: Save the AI-generated artwork directly\n- **⚡ Responsive Drawing**: Low-latency drawing with Ink API support\n- **🌈 Colorful Generation Feedback**: Beautiful multi-color glow effects when AI is generating new artwork\n\n## Project Structure\n\n```\n├── backend/\n│ └── index.ts # API endpoint with Gemini integration\n├── frontend/\n│ ├── index.html # Minimal HTML interface\n│ ├── app.js # Main application logic\n│ ├── components/\n│ │ ├── drawing-canvas.js # Canvas Web Component with size control\n│ │ └── control-panel.js # Minimal control panel\n│ └── style.css # Clean, minimal styles\n└── README.md\n```\n\n## Setup\n\n1. **Set the API Key**: Add your Google Gemini API key as an environment variable in Val Town:\n - Go to your Val Town settings\n - Add `GEMINI_API_KEY` with your Google AI Studio API key\n - Get your API key from: https://aistudio.google.com/app/apikey\n\n2. **Set Basic Auth Credentials**: Add Basic Auth environment variables in Val Town:\n - Add `BASIC_AUTH_USERNAME` with your desired username\n - Add `BASIC_AUTH_PASSWORD` with your desired password\n - These credentials will be required to access the application and API\n\n3. **Access the Application**: The application will be available at the HTTP endpoint URL provided by Val Town\n - You'll be prompted for username and password when accessing the site\n\n## Usage\n\n1. **Select Size**: Choose your preferred canvas size (512x512, 768x768, or 1024x1024)\n2. **Draw**: Start sketching - AI automatically generates artwork underneath\n3. **Toggle**: Use \"Show AI Only\" to see the pure AI artwork or your sketch overlay\n4. **Save**: Click \"Save\" to download the AI-generated image\n\n## Controls\n\n- **Clear**: Remove all drawing and generated artwork\n- **Show AI Only / Show Sketch**: Toggle between views\n- **Save**: Download the current AI-generated artwork\n- **Canvas Size**: Change the canvas dimensions\n\n## Keyboard Shortcuts\n\n- `Ctrl/Cmd + N`: Clear the canvas\n- `Ctrl/Cmd + S`: Save the generated image\n\n## Technical Details\n\n- **Frontend**: Vanilla JavaScript with Web Components, Tailwind CSS\n- **Backend**: Deno runtime on Val Town with Hono framework\n- **AI Model**: Google Gemini 2.5 Flash Image Preview\n- **Canvas**: HTML5 Canvas with optimized 2D context for low latency\n- **Generation Feedback**: Colorful visual effects including rainbow glow
