三角折り板金：山道のガードレールのような詩的な変形

Design a bus shelter in the manner of architecten de vylder vinck taillieu, formed from folded triangular metal surfaces. Show a small structure made entirely by folding flat sheet metal into a faceted geometry — a series of triangular planes creased and turned so they become at once wall, roof and bench, with no separate elements and no applied structure. Detail the folds as sharp crisp creases with the sheet's thinness visible at every exposed edge, and the panel joints as simple bolted laps left plainly on show. Show the reference implied in the form: it recalls the folded metal coping and crash barriers of an alpine pass road, ordinary infrastructure elevated into something deliberate. Detail the finish as a plain galvanised or lightly painted metal, matte and unglamorous, already picking up scratches. Show the geometry casting hard triangular shadows on the ground and on itself. Set it on a roadside with a mountain pass behind, guardrails visible in the distance. Photorealistic, faceted, grey metal against green, three-quarter view.
