/* KIROS-TERAPIA — PWA paciente
   Base cálida y oscura (marca personal del terapeuta): fondo marrón oscuro,
   texto crema, serif para títulos + sans para cuerpo. El azul/violeta de
   KIROS queda reservado casi en exclusiva para el búho mascota y un puñado
   de acentos puntuales (botón primario, anillo de progreso semanal). El
   dorado hace de color de racha/logro; el salvia, de "completado".
   Mobile-first; en desktop el contenido queda centrado como una tarjeta. */
