Prompts:
Test 1:
Create a minecraft-style procedural terrain generator using Three.js. Requirements:

Infinite terrain that generates as the player moves
Multiple biomes (forest, desert, snow, mountains) with smooth transitions
Perlin noise for realistic terrain height
Different block types per biome (grass, sand, snow, stone)
Basic player movement with WASD + spacebar to jump
Chunk-based loading system for performance
Day/night cycle with changing lighting
Trees and basic vegetation that spawn based on biome rules
Underground caves using 3D noise
Water at sea level
Make it visually impressive and performant. Use modern Three.js best practices
All on one file so I can run it easily (index.html).

Test 2:

Create a comprehensive stock analysis dashboard in a SINGLE HTML file with inline CSS and JavaScript.

Requirements:
1. Use CDN links for libraries:
Chart.js or Plotly for charts
Axios for API calls
No build tools, everything runs in browser

2. Core Features:
Stock search/ticker input
Real-time price display with sparkline
Key metrics dashboard (PE, volume, market cap, etc)
Interactive price chart with multiple timeframes
Visualization of price movements or volume
Watchlist functionality (stored in localStorage)
Technical indicators overlay

3. Use FREE APIs that work from browser:
Alpha Vantage (requires free API key)

4. Make it look professional with:
Dark mode financial theme
Responsive grid layout
Smooth animations
Loading states
Error handling

Everything must work by simply opening the HTML file in a browser.
