   equivalent exists elsewhere on this site. Reuses the same design tokens as styles.css (--bg,
   --bg-elevated, --text, --accent, --border, --radius) rather than inventing its own palette.
   Loaded only on pages with a chat widget (support.html, portal/dashboard.html). */

   than a bare heading, but with the long subhead/eyebrow dropped and padding cut well below
   .hero's own default (5rem/4rem), since a one-word title doesn't need that much air around it. */
