Personnalisez « Sceau Baoyu en écriture sigillaire dessiné avec canvas »

Use JS + Canvas to draw a seal-script stamp bearing the traditional Chinese inscription “宝玉”, read from right to left. Base the character forms on the small seal script found in the Shuowen Jiezi; if I provide a reference image, follow it. Do not use a font. Draw every stroke with coordinates and then increase its thickness. Before drawing, list the components that make up each character and specify where each component will be placed on the seal face. Create both white-character and red-character versions. Use cinnabar-colored seal paste, add a subtle carved texture and chipped edges, and use a xuan-paper texture for the background. Export the result as a 1200 × 1200 PNG with a transparent background. When finished, take a screenshot and check whether each character is recognizable and whether the stroke spacing is even; revise the design if any problems are found.
