   carroselectricoscolombia.com — styles.css (PROYECTO DISEÑO)
   -------------------------------------------------------------
   Estilos generales del sitio: colores, tipografías, encabezado,
   portada, noticias, guías, preguntas, contacto, pie y artículos.
   Los estilos propios de la calculadora viven en el proyecto
   CALCULADORA (calculadora.css) y se cargan después de este archivo.
   Los "componentes compartidos" (sección 4) también los usa la
   calculadora: cambiarlos cambia su aspecto, nunca sus cálculos.

   Dirección visual: negro grafito + grises acero, con el azul
   eléctrico como único acento, y vidrio líquido (estilo iOS)
   en botones, tarjetas y paneles.
