   1. reutilizables en varios módulos;
   2. prefijados con dtx-;
   3. documentados en MANUAL_RAPIDO_DTX.md;
   4. probados en tema dark, light y móvil.

   Los estilos exclusivos de un solo módulo deben conservar un prefijo propio,
   por ejemplo: .inventario-evento__selector o .contratacion__resumen.
