Shader Effects

This is the shader effects library you keep in your back pocket for polish passes. It covers the usual suspects: glow and bloom, chromatic aberration, vignettes, film grain, scanlines, glitch effects, dissolve transitions, outlines, and fresnel rim lighting. Most of these are single-function implementations you can drop in and tweak, like a simple distance-based glow or a Gaussian blur bloom. The glitch and dissolve effects are more involved and look surprisingly good for how little code they need. The chromatic aberration comes in both uniform and radial versions, which is the right call since radial looks way better for most use cases. If you're doing any kind of post-processing or stylized rendering, you'll recognize these patterns immediately and probably grab a few to customize.
