# Wallust version compatibility helpers
#
# Purpose:
# - Wallust v3 reads ~/.config/wallust/wallust.toml (this repo ships a v3 config)
# - Wallust v4 alpha uses a different config schema; users frequently install it
#   via wallust-git, which will fail to parse the v3 config.
#
# This file detects Wallust major version and sets arrays used by scripts:
# - wallust_args: args to pass to wallust for wallpaper-derived palette generation
# - wallust_kitty_args: args to pass to wallust for kitty-only palette generation
