/* LS-Contact — Estilos do Formulário
   =================================================

   HERANÇA DE TEMA
   ---------------
   Tenta herdar variáveis CSS dos temas mais comuns.
   Se o tema não expuser nenhuma, usa os fallbacks fixos.

   FOCO ACESSÍVEL
   --------------
   --lsc-focus-ring-color e --lsc-focus-ring-gap são definidos
   em tempo de execução pelo ls-contact.js, que mede a luminosidade
   real do fundo do formulário (fórmula WCAG) e decide:
     fundo escuro → anel branco + gap preto
     fundo claro  → anel preto  + gap branco
   Funciona em qualquer tema, sem conhecer nomes de classe.
