/* ── CLOSING WORLD / HIDDEN ENTRY ───────────────────────────── */
/* ── CLOSING WORLD ────────────────────────────────────────────
   The image is a world layer, not a poster or footer card.

   Architecture:
   - .section--closing-world  tall scroll container (220vh)
   - .closing-world           sticky viewport-height layer (z-index 0)
   - .closing-world__image    the actual image — starts at opacity 0,
                               animated to ~0.72 by JS on scroll
   - .closing-world__content  text overlay, positioned relative,
                               appears after the image establishes
   - .closing-world__hotspot  touch-friendly hidden entry (56×56px)

   Image format guidance:
     Master size:   1800 × 2700 px (portrait — fills tall mobile too)
     Format:        WebP (primary) + PNG fallback
     Composition:   subject (cabin/road) slightly below center;
                    generous empty sky/negative space above for
                    the parallax reveal to feel intentional
     background-position: center 62%  (shows cabin, not sky, by default)
