Detailed Description

Longitudinal cross-section renderer for a path traced across the 2D surface mesh. Plain QWidget + QPainter (chart-like, not map-like), mirroring ProfilePlotWidget's scaffolding (plotRect / dataToPixel / zoom-pan / legend + timestamp drag overlays) but with continuous ground + water lines instead of node/link glyphs.

Render passes (z-order, low → high):

1. background + axes (x = Distance, y = Elevation)
2. soil fill — ground polyline down to the plot floor (broken at off-mesh NaN gaps)
3. max-depth envelope — band (ground → ground+maxDepth) + line
4. animated depth fill — ground → ground+depthNow
5. animated water-surface line — ground+depthNow
6. ground line (crisp terrain edge over the soil)
7. legend + timestamp overlay

Geometry (chainage/ground/maxDepth) is static once set via setProfile(); only depthNow animates — push it cheaply per frame with setCurrentDepths().
