   Portfólio de Lucas Nishimura
   Linguagem visual: dossiê técnico. Papel manila, tinta de arquivo, carimbo
   de status, identificador em mono. O rastro de decisão é o assunto, então
   é ele que dita a forma.

   Temas: :root carrega a paleta clara completa. O escuro é redefinido em
   dois lugares (preferência de sistema e escolha explícita) e SÓ mexe em
   tokens. Nenhuma cor nasce dentro de um bloco de tema.
