/* El calendario de un flujo de aprobación (docs/flujos-aprobacion.md, «Calendario»), prefijo fcal-.
   Reglas de la casa: colores SÓLIDOS (sin degradados), cielo azul y pastel con las variables del
   tema (el modo oscuro viene solo); el color de cada flujo llega por .flu-color-* (--flu-c, --flu-bg).
   Movimiento: los días entran con 240 ms y 25 ms de escalón, y su barrita «se llena» de 0 a lo suyo
   en 600 ms con --ease-out. Con prefers-reduced-motion los días solo aparecen y la barrita ya está llena.
   En el teléfono (≤ 640 px) la cuadrícula no cabe: se ve una lista por día. */
