/* ThynkIA 08/11/2026: home "Antes y después de un agente" (V4).
   White window: the average ROI on a dark card, beside one table (before, with an agent, change).
   Plays once when it reaches the screen: js/reveal.js adds .is-in to [data-play]; the 322 counts up (site.js data-count).
   The starting (hidden) states only apply while reveal.js runs (html.tk-rv), so without it everything simply shows. */
