/* GULLBERG sanatorium - the skin over portal's own stylesheet
   (site.yaml `stylesheet`, loaded after main.css, so these rules win).

   One idea: a sanatorium from the thirties. Lime-washed plaster, pine
   green for what is ruled and pressed, brass for what leads somewhere,
   Futura capitals spaced like the wordmark for what is asked, and a
   calm serif for what is said. Both colour schemes are drawn; the page
   follows the reader's. */
