/* ---------- Page hero variant ---------- */
/* styles.css adds a 1920x1080 hero-image background on .page-hero::before at
   30% opacity as decoration. Pages with $preload_hero=true already have that
   image in cache, so it paints instantly. The blog listing doesn't preload
   the hero (it has no use for it visually), so that background is discovered
   late via the async-loaded stylesheet and paints at ~7s — Lighthouse locks
   onto it as the LCP element and tanks the score. Suppress the pseudo on
   blog pages; the solid dark --color-dark background of .page-hero is
   enough on its own. */
