4242 Here are spherical harmonic transforms reimplemented from scratch as WebGPU compute shaders, modeled on [SHTNS](https://nschaeff.bitbucket.io/shtns/), together with a live reaction-diffusion solver built on them: Turing patterns forming on a sphere, with diffusion handled implicitly in spectral space where the Laplace-Beltrami operator is diagonal. turing-surface extends the solver from the round sphere to closed surfaces given by spherical-harmonic embeddings, and turing-surface-cache narrows it to a discrete menu of parameter choices whose solutions at a chosen end time are shared between all visitors through a cloud cache.
