# post-apply hook for the nag_screen mod.
# Runs after nag_screen patches are applied. Provided env: MOD_CONF, STASH_DIR,
# CONFD_DIR. Replaces the minified proxmoxlib with a symlink to the patched
# unminified copy so the browser serves the patched code. The original minified
# file is stashed (it is a non-patch binary replacement, so `patch -R` cannot
# restore it). Exit codes: 0 = no change, 100 = changed, other = error.
