/* Pico Race — the public site.
 *
 * The palette and the two faces are the game's, straight out of `DESIGN.md`
 * and `art/pixel-ui-kit/`. What is deliberately *not* the game's is the layout
 * discipline: the app composes in canvas pixels and multiplies by a whole
 * number, because it is a fixed-resolution picture. A web page is not, and
 * pretending otherwise gives you a site that is unreadable on a phone.
 *
 * So: brand at the edges, ordinary responsive typography in the middle. The
 * one place that matters most is the legal pages, and there the rule is
 * legibility beats character — see `--face-prose` below.
