/* Erisen — HOME v2 (23/09/2026). Folha própria da home; as páginas internas seguem em erisen-site.css
   até a aprovação visual. Estrutura do design system "Tesla" (design-studio/references/design-systems/tesla):
   subtração radical, mídia em tela cheia, zero sombra, zero gradiente de interface, raio de 4px,
   um único acento, transição de 0,33 s em cubic-bezier(0.5, 0, 0, 0.75). Neutros Tesla em modo escuro;
   o acento é o violeta-azulado da marca (--signal, já medido 10,2:1 sobre o preto), não o azul Tesla —
   o brief V2 §11 pede "um accent violeta-azulado extremamente controlado". */
