 * The home entry card summary, started with the other cold-boot reads instead
 * of after the session list (BUG-1127). The summary does not depend on the
 * session list; Home used to wait for it only because its effect was gated on
 * `sessionListSettled`. One read per cold boot: Home takes it once, and a
 * later call (account switch, retry) reads fresh. Failures read as null, which
 * keeps the card on its default labels, exactly as before.
