The owner's engraving-style chameleon drawing, traced to three colours (ink, paper,
FigCraft green #02da96) on the shared 512-unit tile. assets/app-icon/figcraft.svg is the
master; cargo xtask icon now renders the PNGs (macOS grid), the hicolor theme and the .ico
(tight crop, 16-256 px) from it with resvg instead of drawing the old geometric mark.
Off macOS the window icon uses the tight 256 px render.
