   Casca Vercel — login, header com botões, telas de boot/erro.

   IMPORTANTE: as variaveis a seguir sao apenas DEFAULTS de fallback.
   O viewer.js sobrescreve TODAS elas via document.documentElement.style
   antes de mostrar qualquer tela, usando as cores publicadas em
   /clientes/<slug>.json. Assim a tela de login fica no MESMO tema do
   relatorio (sem "flash" claro/escuro).
