-- arm, every site that closes one must disarm, and disarm must be a no-op on
-- desktop where the hosted save editor depends on text input staying on
-- (tools/save-editor/Kit.lua, #529).  A touch screen also has no ctrl+V, so
-- the prompt grew a PASTE chip; both paste paths share _pasteIndexUrl and
-- both honor the whitespace strip and the MAX_INDEX_URL cap.
