Enhanced Texture Generation Pipeline:

Circuit JSON → circuit-to-svg → SVG → resvg-wasm → PNG → Three.js Texture

• Quality Presets - low, medium, high quality options
• Texture Caching - LRU cache to avoid regenerating identical textures
• Better Fallback - More realistic PCB patterns when resvg-wasm fails

Visual Enhancements:

• Realistic PCB Pattern - Copper traces, gold pads, brown vias
• Better Canvas Fallback - More detailed PCB-like patterns
• Optimized Texture Settings - Better visual quality
