/* Hill Router in the house style.

   The tokens (colours, type and spacing scales, radius, shadow) are
   house-style/tokens.css: a copy of
   https://robinmanhaeve.be/house-style/tokens.css, whose
   --house-style-version says which one. Don't edit the copy; replace it whole
   when the house style changes. HOUSE-STYLE.md in the personal-site
   repository says how to use it; this app follows its "In a web app with a
   map" section.

   What that means here: paper and ink, Figtree, rules rather than boxes, a
   3 px radius and a shadow only on what floats above the page. Magenta is the
   course, wherever it shows: on the map, as its profile, as its row in the
   list. Elsewhere in the interface it is only the focus ring and a link's
   underline on hover. Light and dark follow the system through the tokens'
   light-dark() pairs. */
