/* Calculadora nutricional en pestañas (calculadora-objetivo.html), 25-oct-2026.
   Antonio: «Junta la anterior calculadora con esta y con las del IMC u otras
   calculadoras de pacotilla... en diferentes pestañas y así es algo más
   completa». Va después de calculadora.css y sigue el dibujo de Gasto por
   actividad (css/gasto-actividad.css): bloques blancos, campos grandes con
   la unidad dentro. El acento es el amarillo de la app (css/site-theme.css)
   y los macros llevan los colores de siempre (rojo, ámbar, azul). Todo con
   el prefijo co- para que el theme de las páginas sueltas no lo pise. */
