Research direction

Start by locating the implementation and argument handling for --clip-bounding-box, then trace how GeoJSON features are clipped. Define the expected behavior for a GeoJSON Polygon, including its input form and edge cases, and add coverage for polygon clipping before confirming the resulting vector tiles match the requested shape.
