/* ============================================================
   HERO CARD — isladjan-style "3D" card, tailored to csurette.com
   Recipe: flat solid face + a clip-path'd sibling strip that fakes
   an extruded side edge + 2px ink borders + pixel/mono type.
   Scoped to .hero-card so it can be dropped into index.html later.

/* ---------- floating card wrappers ----------
   The parallax scene is a fixed layer, so every card overlay is fixed
   too, each fading in/out over its own scroll window (data-show /
   data-hide, read by card.js): the hero card lingers pinned over the
   first stretch of scroll before fading (instead of scrolling away
   instantly), the sky card owns screen two, the moon card screen
   three. z-index 6 clears the parallax svg (3), scrollElement (4) and
   footer (5), but stays below the pop-out menu (90) and header pills
   (100) so the nav is always reachable. pointer-events are off while
   hidden so an invisible card never eats clicks meant for the page. */
