+  # they're loaded into (hyprctl plugin load checks a build-hash), so both
+  # the dev shell and the packaged plugin below build against `pkgs.hyprland`
+  # from THIS SAME input, guaranteeing they match each other. Pinned to the
+  # exact revision terra's homelab flake currently locks for nixos-26.05 for
