Comprehensive guide for optimizing React Three Fiber and Poimandres ecosystem code across 70+ rules.

• Covers 12 priority-ranked categories from performance and re-renders (critical) through physics and debug tools, with rule prefixes for quick reference
• Emphasizes avoiding setState in useFrame, isolating React state, using Zustand selectors, and memoizing expensive components to prevent excessive re-renders
• Includes patterns for useFrame animation with delta time, Drei helpers (useGLTF, useTexture, Environment), Suspense loading, and post-processing effects
• Provides code examples for common pitfalls: direct ref mutation instead of state updates, visibility toggling instead of remounting, and transient subscriptions for continuous values
