The save button now reads Save in the composer, Update when editing, and
Comment in the comment editor, with a Cmd/Ctrl+Enter chip inside it that
is
hidden on coarse pointers. Saving keeps the verb and swaps the chip for
a
spinner in the same grid cell, so the button no longer changes width;
the
"Saving..." string is removed from every locale. Hosts that close after
saving hold a short "Saved" confirmation while the caches refresh, then
reset and close; the in-place composer clears immediately as before.
