/* --------------------------------------------------------------- RESET ---
   Blindaje frente al tema de WordPress. La especificidad está calibrada a
   propósito en (0,1,0): la aporta «.fdc» y :where() no suma nada.

     tema:        h2 { ... }            (0,0,1)  ← PIERDE contra el reset
     reset:       .fdc :where(h2)       (0,1,0)
     componente:  .fdc-h2 { ... }       (0,1,0)  ← GANA por ir después

   Así el reset neutraliza los selectores de etiqueta del tema (que sí llegan
   hasta aquí) pero nunca estorba a los estilos propios. Un reset de
   especificidad cero no bastaría: el tema le ganaría. Uno de (0,1,1) —como
   «.fdc h2»— sería demasiado y aplastaría a los componentes. */
