/* Nilfors Studio — the shell every page shares.
   Deliberately plain: reset, theme, header, footer, long-form text. Nothing in
   here belongs to a particular project, because projects will not look alike.
   A project styles itself in its own stylesheet, loaded after this one.

   No web fonts, no CDNs, no analytics: the privacy policies claim we collect
   nothing, and a third-party font request would quietly make that untrue. */
