/* ===========================================================================
   app.bundle.css - a UI nova (entelecy-web-suite) para /api e /contato.

   Montado de Entelecy.Site/entelecy-web-suite:
     src/foundation.css            ordem das camadas + reset + base
     src/tokens.css                paleta, escalas, raios
     src/components.css            header, nav, botoes, cards, footer
     examples/api/page.css         so a pagina da API
     examples/contato/page.css     so a pagina de contato

   DUAS adaptacoes, ambas deliberadas:
   1. [data-theme="night"|"day"] viraram "dark"|"light" - a chave localStorage
      'theme' desta casa ja guarda dark/light, e quem ja escolheu um tema nao
      pode perder a escolha por causa de renomeacao.
   2. As @font-face vieram do site.bundle.css: as woff2 sao auto-hospedadas em
      /fonts/ e a suite as assume disponiveis, sem declara-las.

   site.bundle.css continua servindo o RESTO do site (home, loom, chat) e nao
   foi tocado - este arquivo e adicional, carregado so pelo _LayoutSuite.

   REGERAR: python scratchpad/bundle-web.py
