Resolution Note:
For WebGL, the shaders in the project use target 4.5, and WebGL only supports up to 3.0.
For WebGPU, there are shaders that error from using older URP functions, resulting in shader compilation errors in the build. Once fixed they seem to run correctly with WebGPU.
Firefox has other bugs preventing the project from working that are being worked on by Mozilla and are unrelated to the shaders.
Safari only started supporting WebGPU since Safari 26, which shipped recently.
