/**

 *
 * Plain CSS, no script. A light warm band. Phones: a stack of photo cards, story always shown.
 * Desktop: a row of tall panels - one open (wide, with its story), the rest
 * slim strips with a vertical label; hovering or keyboard focus opens a
 * panel, and the flex-grow change animates the widths. Logical properties
 * keep it correct in RTL; motion stops under prefers-reduced-motion.
