/* Validated.Directory 2.0.0 · Why did AI mix me up with someone else? (DIR 2.0.0 part D, BEA-432). Loads after
   /learn/_guide/guide.css. The main act: two made-up businesses with close names; the AI's reading runs to both as two
   threads that twist together, and its answer blends them; the owner's site states its town, state and phone and links
   its own pages; the threads come apart and the answer comes back whole. Steps follow the scroll and reverse; only
   opacity and transform move. Motion only under html.m. Reduced motion and scripts off: the five steps as a list and
   the map at its end, the old words struck beside the new. */
