+# Waybar custom/pacdiff: shows count of unresolved .pacnew/.pacsave files.
+# Source of truth is `pacdiff -o` (output mode — lists differing files,
+# does nothing). Hidden when zero. Mako fires once when the count goes
+# from "no problems" to "non-zero" (i.e. on the post-`pacman -Syu`
+# settle), so you're nudged exactly once per upgrade wave.
+#
+# Click handler runs `sudo DIFFPROG='nvim -d' pacdiff` in a floating
+# ghostty.
