# FollowsColorScheme=true is a KDE key: only Plasma rewrites the embedded

# Rewriting that string on disk would mean a copy of all 6101 files per
# wallpaper — 75MB across the set, and a 15MB rm -rf + cp inside
# theme-apply on every switch, which is the one path that has to stay
# quick. quickshell tints these at draw time instead (ColorOverlay against
# base05, the same trick the tray uses), so the launcher follows the
# palette live and nothing is copied. monoIcons below hands it the prefix
# that identifies a YAMIS icon.
#
# Consequence: GTK apps still see #d8dee9. That is fine on these dark
# themes, and it is the only consumer that reads these files directly.
