/* ============================================================
   Dresden Goehner — v4 "Evidence dossier, in motion"
   Paper dossier with dark poster plates bound in.
   Motion grammar (from the reference sites, translated):
   scroll changes state — reveals, a chapter readout, counting
   numbers, a band that destabilises then resolves. No scroll
   is ever hijacked; without JS everything is already final.
