"""Example: 3D Plot of Multiple Cross-Sections Along a Blade Span (HTML).

Reads a layout CSV listing (spanwise_location, section_name) pairs, loads
each section's VABS input (.sg) and analysis result (.sg.K), then renders
them as an interactive 3D plotly figure written to an HTML file. Open the
HTML in a browser to rotate / zoom / pan smoothly even for dense meshes.
