// «Capa» · gpt-6-sol (medium)
// A heroic red cape hanging from a simple wooden coat stand: a long flowing red cloth with darker folds and a gold clasp with a blue gem at the top, the hem reaching near the floor; the stand has three short feet. It stands upright on the floor (z=0), facing front (-y), centered, chunky and readable.
