Svelte not importing fonts

I store fonts in static/fonts

Here is index.css

@font-face {
  font-family: 'SpaceMono Regular';
  src: url('fonts/SpaceMono-Regular.tts');
}

@font-face {
  font-family: 'SpaceMono Bold';
  src: url('fonts/SpaceMono-Bold.tts');
}

Result:

SvelteKitError: Not found: /fonts/SpaceMono-Regular.tts

I've tried to move fonts into src, into src/lib, add them via <style> in +layout.svelte, change url from fonts/SpaceMono-Regular.tts to static/fonts/SpaceMono-Regular.tts, but i still getting same error

Vite probably cannot handle the URL like this.
Use a relative path (./ and ../) or use the $lib alias (which points to the src/lib directory).

E.g.

@font-face {
  /* ... */
  src: url('../../fonts/SpaceMono-Regular.tts');
}

@font-face {
  /* ... */
  src: url('$lib/fonts/SpaceMono-Regular.tts');
}
