   El atributo `hidden` tiene que ganar SIEMPRE.

   El navegador oculta [hidden] con una regla `display:none` de su hoja de
   estilos, que tiene la prioridad más baja de todas: en cuanto una clase
   nuestra declara `display:grid` o `display:flex`, el elemento se ve aunque
   el JavaScript lo haya marcado como oculto.

   Sin esta regla, el bloque "Calculando tu comparativa…" era visible desde que
   cargaba la página y no se iba nunca, y lo mismo les pasaba a los campos de
   excedentes, a la potencia P2 y al panel de resultados.
