/* Layout concept: no divider lines between sections - rhythm comes from
   alternating soft background bands, generous consistent spacing, and one
   repeated card/shadow language throughout. Interactivity lives in three
   places: a looping live-demo widget in the hero, a clickable process
   stepper, and a before/after toggle with animated counting. */
