/* Research department site, Option D "Almanac": plain CSS, no framework.
   One unhurried reading column of dated entries, broken by wide image plates;
   each page opens on a pale wash (the horizon) with its plate across the
   wash's lower edge. Every colour, size and space comes from /css/tokens.css,
   which the build copies from the active brand's token file
   (design/tokens-<brand>.css). This file holds no colour values of its own.
   Breakpoints: 600px (narrow), 820px (medium), 1200px (one-row header);
   custom properties cannot be read inside @media, so the numbers are written
   out here. */
