   THEME OVERRIDES — CAPA DE REPAINT QUIRÚRGICO

   REGLA DE ORO: solo tocamos colores, fondos, bordes, tipografía

   NUNCA tocamos:
     - padding/width/overflow de tablas, forms, inputs, botones
     - max-height, table-layout, display de containers funcionales
     - .table-viewport-container, .table-container, .products-table
     - .calculator*, .filters*, .search*, .pagination*
