# --- Target selection (VM vs. an already-themed local laptop) ---------
#
# Scripts from 06- onward can act on either the libvirt VM (over SSH) or
# directly on a local machine that already has the same ML4W dotfiles
# profile installed. TARGET picks which; default is "vm" to match the
# existing behavior of those scripts.
TARGET="vm"

# Scans "$@" for a --vm / --local flag, sets TARGET accordingly, and
# leaves the remaining arguments in the global PARSED_ARGS array for the
# caller to re-collect. Must be called directly (NOT inside a `<(...)`
# process substitution / command substitution), since those run in a
# subshell and the TARGET assignment would not survive. Usage in a
# script, after `source ./00-config.sh`:
#
#   parse_target_flag "$@"
#   set -- "${PARSED_ARGS[@]+"${PARSED_ARGS[@]}"}"
