I love this design, especially as it takes advantage of the Zig build chain; I expect re-builds will be fast enough that you essentially get JS-style hot reloading in the dev cycle. Now we just need https://github.com/air-verse/air for Zig (Ziex has one built into its CLI, but that's only for Ziex)...
Looking forward to seeing some benchmarks!

Tools like HivisionIDPhotos, dpar39/ppp, and commercial services like dreamega.ai and photoaid.com all need to solve the same core problem: given an uploaded portrait, detect the face accurately enough to auto-crop to spec.
