   Margo Café — Av. Sonora 226, Col. Centro, Fresnillo, Zac.
   Estilo tomado de foto real del local: estructura industrial (acero
   negro + blanco + mármol), lámparas de cobre y una cortina de hojas
   colgantes. Base neutra (crudo/blanco) + verde de vid como color de
   acción + cobre como acento puntual — vistoso sin cansar la vista.
