/* ==========================================================================
   REACT BITS: StarBorder & GlareHover Effects
   III Fórum Fiscal Angolano — Implementação Refinada
   Regras Estritas Atendidas:
   1. APENAS NO HOVER DO CARD: Em repouso, o efeito está 100% invisível (opacity: 0).
   2. ESTRITAMENTE NA BORDA: O brilho viaja exclusivamente ao longo do contorno (1.5px),
      sem vazar nem projetar luzes sobre o centro do card, textos ou logótipos.
   3. NENHUM LOOP COLETIVO: O efeito só acende e roda quando o cursor entra no card específico.
