If you can tolerate the (fairly minor) SEO consequences, just render on the client exclusively and fetch data via http calls. I've made small but quite interactive websites with entirely static Svelte + some router (routify/sveltekit/etc.) SPA that just uses http calls for whatever the server needs to be involved in. It's not the right choice for everything, but for some things it works excellently. With a relatively lightweight frontend like Svelte, as well as splitting the SPA into multiple bundles (so it's in some ways not an SPA anymore) makes it perfectly usably snappy even over 200+ms latency, and very fast over a normal connection.

Ignoring for a moment that most websites don't need any interactivity: Even for those that need it, for almost any of them something JQuery-like is more than enough. You really, really, really don't need the latest super big framework.

Most websites don't need an interactive experience on the client, for what is static content.
