In a channel, a DM, or a room, the chip of a sender that is a locked contact reads 🔒 Name (⚿ on the PicoCalc), in the place of the ★ on our own chip. The transcript cache now compares the locks, so a ^K or a lock from the node page redraws the chips on the next paint. The padlock is one constant, marks.LOCK_ICON, shared with the Contacts list.
