Technical blueprint poster of the exact single D20 / icosahedral die from the reference image, preserving its geometry, proportions, triangular faces, silhouette and visible numbers. Crisp white engineering line art on a deep cobalt-blue blueprint background with a subtle fine grid. Flat 2D technical drafting style, orthographic projection, precise geometric contours, construction lines, centerlines, projection guides, dimension lines, arrows and minimal technical annotations. Large central D20 technical view, plus 3 small inset orthographic views: FRONT, TOP, RIGHT. Minimal title block: "D20 DÉ À 20 FACES", "OBJET: D20", "UNITÉ: mm". Clean professional industrial engineering drawing, balanced layout, generous negative space, thin white border. White lines only, blue background only. No shading, no gradients, no lighting, no reflections, no realistic materials, no 3D render, no perspective distortion, no people, no hands, no additional objects, no extra dice, no decorative elements. --chaos 0 --ar 3:4 --raw --stylize 75 --profile 7rp8tg2 --v 8.2
