/* ============================================================
   APPROACH A — CARD FLIP (center-pivoted rotateY 180°)
   ============================================================
   The .flip-card rotates about its centre on the Y axis. The back
   face is pre-rotated 180° so when the card is at 0° we see the
   front; at 180° the front is hidden (backface-visibility) and
   the back lands face-up. Reads as flipping a card to show the
   other side — the metaphor for "two sides of the same person".

   Perspective lives on the .flip-stage so the rotation gets a
   3D feel rather than a 2D scaleX. Tuned around the 1920×1080
   design size — lower perspective = more distortion, higher
   = flatter.
