Slice AU.6 — renders a generated 2D triangular mesh on the canvas.

Rendering is handled entirely by SWMM2DMeshQSGRenderer (a QQuickItem inside MapCanvas's QQuickWidget), which replaces the former per-triangle QPainter path. All scene-space geometry is pre-computed into the public m_scene* caches by rebuildSceneGeometry(); the renderer reads them directly.

Elevation visualisation:

• Filled triangles: terrain colour ramp (deep-blue → near-white) × slope-based hillshade.
• Edges: colour-mapped by slope; steep breaks rendered wider.
• Nodes: SWMM-coupled (tagged) vertices; off by default (setShowMeshNodes).
