+# trash — move files to the Trash following the FreeDesktop.org Trash Spec 1.0.
+#
+# Chooses the correct trash directory regardless of distro / desktop:
+#   * Items on the same filesystem as $HOME go to the "home trash":
+#       ${XDG_DATA_HOME:-$HOME/.local/share}/Trash
+#   * Items on a different filesystem go to a top-dir trash on that mount:
+#       <mount>/.Trash/$uid  (if it is a valid, sticky, non-symlink dir)
+#       <mount>/.Trash-$uid  (fallback, always valid to create)
+#
+# Also writes the matching .trashinfo metadata so file managers actually
+# display and can restore the trashed items.
