# hammer-edit — editor de código REAL para el distro: Adwaita + GtkSourceView, abrir/guardar/guardar-como
# (GtkFileDialog), resaltado por extensión, números de línea, apertura de archivos desde la CLI. Link 100%
# estático (gtk4+libadwaita+gtksourceview). No es una demo: es una app instalable y usable.
