Create an extremely large ASCII art optical illusion using only standard keyboard characters. Depict an impossible 3D Penrose triangle whose three rectangular beams connect in a continuous, self-closing loop. Use hundreds of characters per line, intricate perspective, precise monospaced alignment, and dense geometric line work. Output ONLY raw plain text, with no image, no Markdown explanations, and no introductory text. Make the illusion structurally coherent and preserve the impossible geometry.
