/*
 * site.css — Shadewash's own site.
 *
 * No web fonts, no CDN, no analytics, no third-party anything: the page makes
 * exactly zero requests it did not ship with. That is not austerity for its
 * own sake. A product whose whole claim is "nothing leaves your device" cannot
 * sensibly have a marketing site that loads five trackers to say so, and the
 * Leak Check tab would be a hypocrite if this page phoned home while a reader
 * used it. Everything here is one stylesheet, two scripts and seven PNGs.
 *
 * Tokens match src/options/options.css so the site and the product look like
 * one thing.
