   pseudo-element (works on desktop AND iOS Safari — background-attachment:fixed is
   ignored there). Every band becomes a translucent dark-glass panel so the photo
   shows through everywhere while all text stays legible (light copy on dark tint).
   Tints run 0.62→0.86 — strong enough that even the photo's bright glow-nodes,
   wherever they land behind a panel, never drop text below readable contrast.
