/*
 * Night Desk: static pages (home, case pages, how to play, leaderboard,
 * about, privacy, 404).
 *
 * The page is a detective's desk late at night: a dark header strip, a
 * lamp-lit wood desk for the main area, and the desk's front edge as the
 * footer. Content sits on physical props: manila folders, typed paper
 * sheets, index cards and sticky notes. Props get real shadows; chrome
 * (header, footer, breadcrumb) stays flat.
 *
 * Colours come only from the NIGHT DESK tokens in tokens.css. Shadows use
 * the shadow tokens (--prop-shadow, --pin-shadow, --paper-shadow) or the
 * one shadow colour, rgb(var(--shade) / alpha), which also draws the wood
 * grain lines. Everything here is scoped to
 * the generated pages (body.site); the case app never loads this file. The
 * last section styles the design-system reference page (/style-guide.html,
 * classes sg-*).
