/* The blog's whole design system. One static file because `style-src 'self'`
   forbids inline styles, and a stylesheet built from tenant data would be a
   stylesheet a tenant can inject into.

   No webfont: `font-src 'self'` and a self-hosted font would be a network
   round trip on a page whose only job is to render text fast. The stack starts
   at the same Geist the dashboard uses when the reader happens to have it. */
