SSR is still an experimental feature in Vite and isnt strictly necessary for us because we serve our code as static files instead of from a live server. Whereas traditional frameworks like React and Vue do the bulk of their work in the browser, Svelte shifts that work into a compile step that happens when you build your app. In the case of your repro - If you move svelte-toolbox from a dependency to a devdependency, everything seems fine. In SvelteKit, you could have a function called load in pages and components, which runs before a component is created. It's just a client framework.
