/**
 * Shared stylesheet for the guides cluster.
 *
 * index.html and leaderboards.html each carry their own inline <style>, which
 * was fine at two pages and stops being fine at nine. The guides are one
 * template repeated, so the tokens and the chrome live here once and every
 * guide links it. Anything a single page needs alone stays inline on that page.
 *
 * Tokens are copied from index.html rather than reinvented — same sand, same
 * ranger green, same rust that turns tritium in the dark.
