purely to learn WebGPU and under the data structure that I've seen
incredible demos on.
Tons of wonderful information is available online:

Demo Canvas above. This demo is not fully representative of the quality of radiance cascades. Of the many known issues (color banding, light leakage), fixes have been developed which I have not implemented here.
