Strange error in playground

[frederikhors]

I'm getting this error in the playground: https://svelte.dev/playground/c0d6167cde154d7d85265909475024fb?version=5.33.14

Why?

Error compiling component
Failed to import $app@latest. Are you sure the package exists?

You cannot use virtual SvelteKit modules in the Playground.

• REPL: "Error fetching "$app" from unpkg. Does the package exist?" svelte.dev#1230 (déjà vu)
• Support for SvelteKit in REPL svelte.dev#844

Oh wow. Sorry. Maybe a better error can help slow brains like mine! Sorry!
