/*
 * Guide pages: plain HTML, no JavaScript, no Vue.
 *
 * These exist for a crawler that renders nothing. The SPA's own routes show it an empty shell,
 * so the pages that answer "how is a building charge calculated" must be complete on the
 * wire. Tokens mirror src/style.css so the two do not drift apart visually; keep them in step.
 *
 * The font is the same Vazirmatn the app ships, copied here because the app's copy lives under
 * /assets with a hash in its name that changes on every build.
