/* =========================================================================
   GUIDE PAGES — long-form reference layout for the AI-search hub
   (/kettlebell-complexes/ and its 3 sub-pages)

   Distinct from the rest of the site on purpose: those pages are short,
   persuasive, mobile-first scrolls built to convert ad/organic traffic in
   one pass. These are dense reference pages built to be read, extracted by
   crawlers, and occasionally skimmed on a wide desktop monitor. Same brand
   tokens (colors, fonts) from styles.css — different structural layout.
   Load this AFTER styles.css.
