It looks like an HTML templating engine. I guess it packages the HTML rendering itself into client side WASM, but I'm not sure if that's an improvement.

I'm not sure what the WASM part does from the website to be honest, at first I thought the server generates the HTML but it seems everything is rendered client side? The architecture page (https://go-app.dev/architecture#app-wasm) describes the basic working of a WASM application, but that's it. There's also pre-rendering (https://go-app.dev/seo) for SEO reasons, so in a sense the project is ALSO a server-side HTML templating system.

That’s kinda mean
