 * /guides (#235). The owner chose, on 2026-10-01, option A "Field notes" for
 * the /guides directory and option C "Trip line" for each article. Copy lives
 * in apps/ios/docs/marketing/guides-sketch. The capsule and footer repeat the
 * homepage's (site.css `.home`) so these pages do not inherit the homepage's
 * hero and bento rules. Pages link /site.css (fonts and tokens) before this file.
