Pardon my ignorance as this is not my world at all but what's this look like in practice?

Are they web apps packaged for desktop apps like Electron apps but using WASM?

wgpu implements just the webgpu part, it's not a full browser with html/css/js/etc. All of the code is native, and the abstraction is pretty thin.

This. Everything is written in native Rust and wgpu has all of the FFI stuff built into it so we don't really have to worry.
