#
# Root cause: hyprmoncfg checks ONLY the file given as --hypr-config for the
# `source = ...monitors.conf` line. On caelestia that line lives in
# hypr-user.conf; hyprland.conf pulls hypr-user.conf in indirectly (and via the
# $cConf variable), which hyprmoncfg does not follow — so it refuses to write
# monitors.conf ("not sourced by hyprland.conf") and the profile never applies.
#
# Fix: point both the daemon (hyprmoncfgd) and the Super+Ctrl+H TUI at
# --hypr-config hypr-user.conf with an absolute --monitors-conf. Idempotent.
