 * RESPONSIVE-FIXES.CSS - Fixes de Responsividad y Coordenadas
 * Ajedrez de Silicio - Consolidación de fixes inline
 * 
 * Este archivo contiene todos los fixes de responsividad que estaban inline en tablero.html
 * 
 * NOTA: Estos estilos complementan los estilos de board.css. Los estilos aquí tienen
 * selectores más específicos (body:not([data-tablet-fix])) y !important para asegurar
 * que se apliquen correctamente cuando el fix de tablet está activo o inactivo.
 * 
 * Los estilos de coordenadas en board.css (líneas 645-831) son más detallados y se
 * mantienen como base. Los estilos aquí son ajustes específicos para el comportamiento
 * condicional basado en data-tablet-fix.
