// Archive view (US06-05): preview what would leave active storage, confirm it
// exactly, watch the transfer, recover an interrupted one, browse what is already
// archived, and bring it back.
//
// Archiving is the only stage that removes originals, so this view never decides
// anything itself: the destination's identity, every blocker, the confirmation
// token, and what recovery may do all come from the server, and an action the
// server would refuse is not offered. Two things follow from that. A medium that
// is not mounted produces an instruction naming it rather than a disabled mystery,
// and an operation whose evidence is ambiguous offers no button at all.
