1. meta[name="theme-color"] no es soportado por Firefox. No hay solución CSS, solo advertencia.
2. content-type para JS debe ser 'text/javascript' en el servidor, no se corrige en CSS.
3. zoom no es soportado por Firefox < 126. Usa transform: scale() para compatibilidad cross-browser.
4. color-adjust está obsoleto, usa print-color-adjust.
