Filament v2: how to integrate Vite Theme Styles into Custom Page

Hi!

I've created a Vite Theme, and the Filament resources pages are working well with this theme.

However, I recently created a custom page, but it's displaying default CSS styles instead of utilizing the styles from the Vite theme.

Could you please advise me on how to ensure that the custom page utilizes the Vite theme's styles?

Thanks in advance!
