/**
 * Reference-guide pages (/guides/*).
 *
 * These are documents, not landing pages: long-form, text-forward, built to be
 * read and to be quoted. They reuse the brand tokens but deliberately drop the
 * marketing-page furniture (full-bleed heroes, bento grids, reveal animation)
 * because none of it helps someone reading an answer.
 *
 * Tokens are redeclared here because /guides pages don't inherit the :root
 * block that lives inline in each of the four original landing pages.
