/* The forge guide: one stylesheet, light and dark, phone first. The page
   reads like a git log, with each section a commit on one line.

   The palette, the fonts and the rules are the forge's own
   (site/assets/style.css, DESIGN.md), and lib/check-css.ts holds this file
   to them: a plain page, square corners, content between 1px rules rather
   than in boxes; Open Sans for the interface, Noto Sans Mono for what is
   copied or compared, Noto Serif for the prose; hierarchy from weight, size
   and colour, never capitals or tracking; one accent (#3148F6) for links,
   the rail, the current entry and the primary button. */

/* == tokens == Every colour, size, weight and family is here; nothing
   below this block names one. */
/* The forge's fonts, copied into fonts/ when the guide is deployed
   (.forge/sites). The sans is preloaded. */
