/* ============================================================================
   DALC — print shop walkthrough (work-printing.html, "Selected work")
   A full-screen, pinned camera flight through the in-house print studio. Scroll
   drives the film; the camera eases to a hold at each station while a frosted
   panel explains that service (LUT Studios' station rhythm), then carries on.

   Default styles are the STATIC layout (no JS / reduced motion): the poster
   frame with every station panel listed under it. print-flight.js adds
   .is-live for the pinned film.
