/* site.css — one paper, one button for every public page (/welcome,

   home and pricing were near-black with square blue buttons while the
   other pages were pure white with default blue links, so they read as
   two sites. Paper is the light default; the welcome page's dark hero is
   kept as a night band only (.night). The app's own font files: the
   Flutter web build copies assets/fonts/ to /assets/assets/fonts/. */
