/* ─────────────────────────────────────────────────────────────
   ui.css · the site, away from the world.

   Dark, quiet, expensive. One deep ground, surfaces a shade above
   it, a gold that is used for exactly one thing at a time, and a
   mint for anything that is alive right now. Bricolage Grotesque for
   the words that carry the page, Inter for the ones you read, a mono
   for numbers and addresses so they line up.

   The layout is plain: a hero with the map in a window, a strip of
   the buildings going past, the numbers, the mechanics as prose, and
   a footer with links in it. One soft light at the top of the page
   and nothing else glowing.

   The class names are the ones the page scripts already emit, so
   the shop, the holdings and the docs restyle without a line of
   JavaScript moving.
