Slice CF.MVP — renders 2D surface-routing depth as a colour-mapped overlay on the canvas. The layer is data-source agnostic: during a run the source is an EngineMesh2DSource driven by SimulationRunner ticks; after the run the source swaps to an HDF5Mesh2DSource reading the engine's CF/UGRID HDF5 file so the user can scrub a time slider back to peak inundation.

Rendering reuses the SceneTri paint pattern from SWMM2DMeshLayer (Slice AU). The only differences:

• Per-triangle colour comes from depth, not elevation, via the inundation colour ramp.
• Dry cells (depth < DRY_DEPTH) draw with alpha = 0 so the underlying SWMM2DMeshLayer terrain shows through.
• No hillshade pass — the wet "sheen" is intentionally flat colour.
