/**
 * ATX Book-Alt — ride alternatives list.
 *
 * Vertical radio list. Each row is a 4-column / 3-row grid:
 *   row 1: [ radio ] [ icon ] [ title ............... price ]
 *   row 2:                    [ note  (wraps)               ]
 *   row 3:                    [ badge (wraps, severity)     ]
 * Note and badge rows collapse to 0 height when absent.
 *
 * Selected state uses the theme's --are-color brand accent.
