/* ═══ PIPEIT PRODUCT EXPLAINERS ═══
   Animated fragments of the real Pipeit application. Design System 2.0 tokens
   only - no second design language, no decorative motion.

   Degradation model: the BASE styles are the final, fully-revealed state. The
   engine adds .xp-live to the root, which is what hides steps and enables the
   sequence. If JavaScript never runs, every explainer renders as a complete,
   readable static diagram. */
