/* ============================================================================
   Marca Bela, design system comum do site (home, Studio, Core e páginas legais).
   Os componentes seguem a forma do design system da página do Core: botões,
   vidro, cartões, selos, cabeçalho de seção, grade de recursos, perguntas,
   campos, menu e rodapé. Cada componente lê dois grupos de tokens:
     1. FORMA (raio, sombra, espaçamento, movimento): iguais em todo o site.
     2. COR (--c-*): mudam com o clima. .theme-day é o Studio, em creme e lavanda;
        .theme-night é o Core, em índigo com brilho. .light dentro do Core volta ao dia.
   Cada página carrega este arquivo e depois o seu (home.css, studio.css, core.css).
