Phase B.RHI of docs/RENDERING_5M_PLAN.md — Qt Quick Scene Graph renderer for SWMMModelLayer. Renders ALL vector layers (lines, subcatchments, node glyphs, gages) via QSGGeometryNode, with selection coloring per class. Native Metal / Vulkan / D3D11 via QRhi underneath; no QPainter, no GL paint engine quirks.

LABELS ARE INTENTIONALLY NOT DRAWN HERE. The label contract (LAYER_STYLING_LABELING_PLAN_2026-08-16) is a hybrid: even when this QSG overlay owns every geometry kind (qsgOwnsKind), text labels are painted by the CPU pass in SWMMLayerItem::paint — screen-space via the shared LabelPainter, deliberately NOT gated on qsgOwnsKind. A pure-QSG glyph pipeline (atlas + text nodes) was evaluated and rejected: the CPU overlay is correct, zoom-stable, and cheap relative to geometry upload. If you add a text pass here, remove the CPU label block in swmmlayeritem.cpp or labels will double-draw.
