   CENTURY AUTO TRAVELS — AI ASSISTANT
   Loaded on every page. Entirely self-contained (its own fixed-position
   button + window), so it can never affect the layout of anything else
   on the page. Reuses the site's existing colour tokens (--gold, --bg-
   elevated, --border-strong, etc. from style.css) so it looks like a
   native part of the site rather than a bolted-on widget.

/* On the homepage only, the hero's own "Scroll" cue sits bottom-right of
   the first screen (site-wide .hero-footer-row, untouched here) — right
   where a plain bottom-right button would land. Rather than move that
   existing element, the button/window lift by this one extra amount
   only on body.page-home, clearing it while staying put on every other
   page. Every offset below is written off this single variable so the
   lift never has to be duplicated per breakpoint. */
