Marked complementary-component limits

The center/radius sequences are selected from actual circle-domain components. Their Hausdorff-convergent subsequence preserves a previously constructed locally uniform map limit.

    Source documentation

    A mark need only be included eventually. Dummy radius-zero disks at its earlier stages do not affect the simultaneous parameter limits.
