- Add TextureLoader class using stb_image for PNG/JPG/etc loading - Integrate TextureLoader with ResourceCache for cached texture loading - Add SpritePass::setTexture() for binding textures to sprites - Add "defaultTexture" config option to load texture at startup - Create assets/textures folder structure - Add 1f440.png (eyes emoji) test texture Visual test confirms textured sprites render correctly. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
