/* Orange Sky Travel — single Trip page styling.
   Layout matches the live Squarespace design: centered trip title (H1),
   trip code (H2), outlined BOOK THIS TRIP button, Heyzine flipbook,
   orange DOWNLOAD TRIPBOOK link.

   The template renders from ACF fields only; the brand orange is the
   single CSS variable below — tweak it to change every accent on the page. */
