4:5 portrait Bureau Field Reading, an analogue meteorological instrument print mounted on aged scientific paper, not a painting and not a landscape. Two hard-edged horizontal colour zones dominate: a vast heavy upper zone for 100% overcast cloud cover, and a soft grey-green lower field for 16.3 C. Almost invisible graph-paper grid beneath the colour, slight horizontal squeegee drag, fine grain leaning east-southeast with 13.2 km/h wind from 299 degrees; one faint secondary rain-grain cue for showers later. One crisp full-width bright amber #fbbf24 datum line sits near the middle for 1013.6 hPa pressure. Bright amber ATMOSPHAERE label upper left with a thin pointer line; near-black lower-left data panel with amber monospace text: NOW 16.3 C / RH 82% / 1013.6 hPa / WIND 13.2 km/h 299 deg / overcast / rain 0.0 mm / OUTLOOK H 19.9 C L 13.9 C showers rain 73% 3.8 mm. Amber circular BRAINHUGGERS BUREAU seal lower right, corner registration crosses, near-black border frame. No figures, no skyline, no photography. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
