/* CAMINHO: frontend/public/admin/assets/admin.css
   Estilo compartilhado por TODAS as paginas do painel administrativo
   (Etapa 3). Reaproveita a paleta de cores ja usada nas telas de espera
   (/shared/css/base.css) para manter uma identidade visual unica da GELFS,
   mas com um layout proprio (barra lateral + conteudo) pensado para telas
   de computador/notebook/tablet - NAO e otimizado para toque como o totem.

   Espaco reservado para a logo oficial da GELFS: ate ela existir, usamos um
   selo com o nome da marca em texto (".admin-logo-placeholder") em vez de
   inventar um simbolo grafico - basta trocar esse bloco por uma <img> mais
   tarde. */
