/* ==========================================================================
   DRYWALL: da laje crua ao teto com luz
   1) cena de tela cheia: a câmera dentro de uma sala, olhando para cima. A
      laje crua recebe a estrutura F-530, as chapas sobem e são parafusadas,
      fita e massa fecham as juntas, o rebaixo desce e a sanca acende. No fecho
      o visitante troca o acabamento ali mesmo;
   2) as três chapas Placo (ST, RU e RF) e onde cada uma entra;
   3) obras da loja;
   4) a calculadora de teto e de parede, com a lista para o WhatsApp.
   A sala é uma caixa 3D em CSS: medidas em pixels vêm do drywall.js
   (--W largura, --H altura, --D fundo, --m um metro).
