game stuff

• Infinite procedural terrain
• Perlin-like noise (3 octaves)
• Textured by height (sand, grass, rock)
• Chunked loading/unloading (32×32 tiles, 2.0f scale)
• Driveable car physics
• Acceleration, braking, friction, max speed
• Smooth steering with rotation
• Terrain-following (y = terrain height + 0.5)
• Dynamic third-person camera
• Follows car with offset
• Adjustable pitch/yaw (currently fixed, but extensible)
• Engine sound
• enginesound.mp3 plays on W/S press
• Smooth volume fade-in/out (exponential easing)
• Loops seamlessly
