/* ---------- LANDING PAGE LAYER ----------
   Loaded AFTER styles.css on the static landing pages (/ai-development,
   /ai-consultancy, /ai-automation, /insights/...). styles.css supplies the
   design tokens, fonts and theming; it also carries one-page-experience
   globals (720vh scroll runway, hidden native cursor) that these ordinary
   article pages must undo — hence the body.lp overrides up top. */
