/* Slice 20: factory and program pages, wave 2 (touch and interaction).
   Builds on 10-factory.css. Scoped to the factory routes or to ef20-* hooks used only in those
   templates. Shared behavior is NOT repeated here: 20-system owns .btn and .chip press states,
   the button ripple and 44px chips on touch; 20-footer owns tap feedback on .steps4 li and .process li.
   Only things that act get a press or hover response: static spec cards stay still.
   Motion is transform/opacity only and is switched off for prefers-reduced-motion at the end.
   JS hooks live in assets/js/parts/20-factory.js. */
