/* ===== The Happy Newspaper — folded broadsheet in CSS 3D (per ANIMATION-SPEC.md) ===========
   Paper 430×580, halves 290 tall. REAR sheet at translateZ(-6px); FRONT sheet swings open on
   the left spine (rotateY -179.4). Bottom halves fold BEHIND on hinges with z-offset origins
   (-3px rear, -9px front) so the folded stack is front-top, rear-top, rear-flap, front-flap.
