The planner clips a rectangular panel grid to the clear area after edge margins. It supports straight rows and half-offset alternate rows, plus a 90-degree orientation change. Each clipped panel is a placement piece; the quantity is not a stock-sheet packing result. Openings and arbitrary room polygons are not supported. Use the drawing to identify edge cuts.
