/*
 * Editorial layout for the guides under public/guides (limitations guides, the

 *
 * The pages still load Tailwind from the CDN for utilities; this file carries
 * the handful of components that Tailwind classes cannot express cleanly
 * (numbered list counters, the hero overlay, the sticky CTA bar) so that the
 * template can be tuned in one place instead of 80-odd files.
 *
 * Type comes from /js/shared.js (Playfair Display for headings, Inter for body).
