/* acesso-ds.css — a tela de acesso
   ================================================================
   Tudo aqui é escopado em `#splash`, e `#splash` some do DOM assim que a
   sessão abre. Então esta folha não pode afetar nenhuma tela do painel, por
   construção — nenhum seletor dela existe fora do login.

   O que ela substitui: a foto de montanha ocupando a tela inteira com um
   cartão escuro flutuando no meio. Bonito e genérico. Agora é uma tela
   partida: a marca de um lado, o acesso do outro, e entre os dois uma malha
   de dados que se move devagar.

   Sobre a "tecnologia" da tela. Nada aqui é biblioteca nem imagem pesada:
   - a malha são 7 linhas e 12 nós em SVG, 3 KB, animados por CSS;
   - a aurora são dois gradientes radiais que derivam de posição;
   - o grão é um feTurbulence em data-uri, 300 bytes, a 3% de opacidade;
   - o cartão usa backdrop-filter, com um fundo sólido de reserva para quem
     não suporta.
   Resultado: a tela abre sem esperar download nenhum além da foto e do logo.

   Movimento: tudo que se mexe está atrás de `prefers-reduced-motion`. Quem
   pediu menos animação no sistema vê a mesma tela, parada.                */
