SwiftUI Metal shader
Halo
A card lit from inside its own edges: four inset bands growing inward, a radial core holding the centre dark, and film grain over the lot. Drag the light on the canvas to move it.

How it works
Halo is a real [[stitchable]] Metal shader, not a video or an image. It runs as a SwiftUI .colorEffect, so it paints any view you attach it to. You shape it with sliders in a live preview, then export the .metal file and the SwiftUI code that uses it, or the React Native and Web version. No MSL to write.
