/*
  GÉR Burkolatok — burkoló iparági demó.
  IRÁNY: a munka maga a látvány. Sötét, mozifilmszerű hero a burkolás
  folyamatáról (ragasztás → lerakás → kész fürdő), alatta folyamatsáv.
  Precíz szakmunka, nem lassú luxus: gérbe vágott sarkú betű, hideg
  kőszürke tónusok, egyetlen terrakotta kiemelés. (Az OROM-demó
  talpas/réz világától szándékosan eltér.)
  Minden mozgás egyetlen lassuló görbét használ (--ease), és csak
  transform/opacity animálódik.
