/*
  Identidad visual: pensada para un consultorio dental, no para un SaaS
  genérico. Paleta clínica (verde azulado profundo) con un acento cálido de
  arena para las acciones principales — evita el verde/azul de "salud"
  genérico y el terracota/crema por defecto de plantillas de IA.
  Tipografía única (Inter) con escala de peso, sin decoración: en una
  herramienta de uso diario la legibilidad y la densidad de datos importan
  más que la personalidad tipográfica.
