The previous nearest-first build captured every deferred visual node as text into a sorted vector, which does not scale: one tomaszewo flora file alone holds 440k model nodes (the scenery has 1M+), so the capture ran the process to ~7 GB and its enumeration never finished. Stream the visual nodes in camera-distance rings instead, with no per-node capture (O(1) memory). The visual pass replays the twin once per ring (nearest first); a node is built only when its squared distance to the camera -- sampled once when the visual phase starts, so the partition is stable across passes -- falls in the current ring, otherwise the rest of its body is skipped in O(1) by jumping over the v6 marker span. Each node is therefore built exactly once, in roughly nearest-first order, through the normal node path (instancing buckets unchanged). Explicit triangles/lines shapes have no single position to ring-test by, so they build in the nearest ring pass only. Reader gains skip_to_node_end() (remembers the served node's end and jumps the cursor there); cParser::skipReplayNode() delegates it down the active include child. Verified: td.scn builds 4 rings, no duplicates, no unexpected tokens, complete ~1s after the infrastructure pass. tomaszewo stays memory-bounded (no OOM, no duplicates) where the capture approach previously hung.
