/* CUIStaggeredReveal - mirrors cui_staggered_reveal.dart: FadeTransition > ScaleTransition > (CUIWiggle >) child.
   Wait staggerStep*index, then scale beginScale -> 1 over 500ms with Curves.easeOutBack while opacity 0 -> 1 with
   Interval(0, .5, easeOut) (= easeOut over the first 250ms). Once landed (delay + duration) the child wiggles:
   angle = sin(v*2pi + phase) * 0.05 rad, v = 0..1 repeating over CUIWiggle's default 450ms, phase = index * 1.1 rad.
   Custom properties: --_delay (ms), --_dur (ms), --_scale, --_phase (rad), speed via --cui-speed.
   Reduced motion (.is-reduced): lands instantly, no wiggle. */
