/* The chrome every page of this site carries: the signage tokens, the type scale, the
   masthead and the section heading.

   Lifted out of index.html when a second page arrived. Two copies of a palette is how one
   page ends up in a different typeface from the next - which is what happened to the
   console, where tokens.css asked for Archivo and nothing loaded it for months.

   Anything belonging to one page only stays in that page. */

/* ---- Tokens -------------------------------------------------------------
   Signage, not stationery. What is being sold is a panel bolted to a wall in a
   corridor, so the page borrows from what hangs beside it: departure boards,
   fire-door plates, timetables. Navy carries the structure, a signal yellow
   does the pointing, and almost nothing is rounded - a sign is cut, not drawn.

   One typeface, worked hard. A display serif over a body sans is the reflex
   pairing; here the contrast is weight and size within a single grotesk, which
   is how a sign gets its hierarchy when it only has one plate to work with. */
