Flip Card Front/Back Face Handling
A CSS 3D flip card pattern where front and back faces share one plane, hide their backfaces, and expose focus-safe fallback behavior.

CSS 3D / Backface Visibility
Front and back faces occupy the same plane, use backface-visibility: hidden, and flip with a focus-safe reduced-motion fallback.
Y-axis rotation
Standard horizontal flip (rotateY). The mirrored back never bleeds through while the card rotates 180°. Keep the perspective wrapper separate from the card transform wrapper.
X-axis rotation
Vertical flip (rotateX) for top-to-bottom card reveal. Same backface mechanics as a Y-flip — only the rotation axis changes, demonstrating that the technique is axis-agnostic.
Opacity crossfade
No rotation — faces crossfade via opacity for dense interfaces and reduced-motion users. Same DOM structure, gentler motion. The proper reduced-motion fallback pattern.
