+# Why this file exists, and why it duplicates hypr/env.lua:
+#
+# The session logs in via "Hyprland (uwsm-managed)", which runs the compositor
+# under the systemd user manager. Variables set with hl.env() in hyprland.lua
+# are exported into the COMPOSITOR's environment -- but NOT into the systemd
+# user manager. Anything started as a user unit (vicinae.service,
+# hyprpolkitagent.service, hyprpaper.service, hyprsunset.service) and every app
+# those units launch would therefore not see them.
+#
+# uwsm sources this file into the systemd activation environment before the
+# session starts, which covers both. Keep the two in sync; hypr/env.lua remains
+# the fallback for the plain (non-uwsm) "Hyprland" session.
