/* biohub / _shared.css

   As oito ferramentas partilham este arquivo, entao ele e o unico lugar
   onde elas mudam de aparencia. Ate aqui ele carregava a propria paleta,
   as proprias fontes e o proprio modo escuro, tudo em literal: era um
   segundo sistema de design vivendo dentro do mesmo dominio.

   Agora ele importa a linguagem. Nada de cor, tipo, raio, sombra ou
   curva nasce mais aqui: o que sobra sao as regras de forma que so estas
   telas tem, e todas elas resolvem para token.

   Os arquivos vem por URL e nao pelo empacotador porque estas paginas
   sao HTML estatico, servido direto de public/. */

/* O controle destas telas E a pilula da linguagem, escrita aqui porque
   estas paginas nao passam pelo empacotador.

   O que saiu, e cada um era um defeito:

     --glass-bg, --glass-border e --glass-shadow, que apontavam para
     tokens de uma paleta que nao existe mais desde que este arquivo
     passou a importar a linguagem: as tres resolviam para nada;

     desfoque de 72px numa pilula de 32px de altura. O raio do desfoque
     precisa caber na caixa, senao o Chrome amostra alem dela e desenha
     um bloco fantasma no primeiro de uma fileira de vizinhos;

     backdrop-filter declarado ANTES da -webkit-, que e a ordem em que o
     minificador guarda so a prefixada e o vidro sai sem desfoque nenhum;

     vinte !important, que existiam para vencer uma cascata que nao
     existe mais.

   A unidade do aglomerado liquido fica FORA: ela e espelho de um blob e
   precisa da propria caixa. Vesti-la de pilula desalinhava as duas
   camadas e as gotas apareciam deslocadas atras dos botoes. */
