/** The tag's lifecycle for one viewer: `set()` once the startup checkpoint has
 *  cleared, `clear()` on teardown so a stray tag can't outlive the pane.
 *  `pane()` is the id teardown reports as this viewer's home.
 *
 *  Split into a claim + a clear because ordering matters: a remote relay's "no
 *  node"/"no running broker" close can still throw AFTER the socket is up, so
 *  the tag is claimed only past that checkpoint — while `clear()` must be safe
 *  to call from a teardown that runs before it was ever claimed. */
