      # del nodo (913G), así que no saltan nunca antes del desalojo. El 2026-08-12
      # el pod fue desalojado tras 21 días por eso. Lo que se acumula son imágenes
      # sin tag: cada vez que upstream republica catthehacker/ubuntu:act-22.04, la
      # anterior (1,5G) queda colgada y nadie la borra.
      # prune SIN -a a propósito: borra solo las dangling, jamás una imagen con tag,
      # así que no vacía la caché de act ni la de buildkit y los builds no se frenan.
