# gtk4-hello — app GTK4 mínima de VALIDACIÓN: prueba que libgtk-4.a (static) es linkeable de verdad.
# Reutiliza el tarball de GTK4 solo como acarreo de [source] (lo ignora); escribe su propio hello.c y
# lo linkea ESTÁTICO contra todo el cierre GTK4 vía `pkg-config --static gtk4`. Si sella, el toolkit
# de GUI del lab es usable por apps, no solo "compila". deps = cierre .pc completo + gtk4.
