## Summary

Deliver `@suaveplan/r3f-shaders` on the genesis branch from scratch at enterprise quality. The package provides a library of custom shader effects and materials for React Three Fiber: hologram, dissolve, outline, rim-light, toon, heat-distortion, and x-ray materials; GLSL utility functions (noise, rotation, gamma correction); a `ShaderMaterial` factory with hot-reload support in dev mode. Each shader is a typed React component that accepts uniform props. Genesis adds structured errors, and 100% coverage.
