モダニズムのバスシェルター：鋼、ガラス、そして純粋なプロポーション

Design a bus shelter in a rigorous mid-century modernist language. Show a precise rectangular frame of slim painted steel sections carrying full-height clear glass panels on three sides, every member the same slender profile and every joint a clean welded mitre. Detail the proportions as the design's entire content: the frame set out on a strict module, the glass panes all identical, the roof overhanging by exactly the same dimension on every side, and the whole composition governed by a single ratio. Show the roof as a thin flat plane in the same painted steel with a fine folded edge. Detail one end panel as solid — a single sheet of enamelled steel in a strong flat colour, a signal red or a deep blue — the only colour in the composition. Show the bench as a simple slatted timber plane on steel supports, aligned exactly with the frame's module. Detail the signage in a clean geometric sans-serif applied directly to the glass. Set it on a clean pavement with a modernist building behind. Photorealistic, rigorous, grey steel with one colour plane, eye-level view.
