            One form submit deploys an entire inter-rack fibre harness: a
            parent <code>FibreTrunk</code> + N cassette devices + N native
            <code>dcim.Cable</code>s linking the source patch-panel RearPort
            to each destination + N <code>TrunkBreakout</code> rows binding
            the cables to the trunk at chosen fibre ranges. The whole batch
            is applied atomically — if any row fails validation, nothing is
            saved. After submit you'll see a preview before anything hits
            the database.
