4:5 portrait Bureau Field Reading, an analogue meteorological instrument print mounted on aged scientific paper, not a painting and not a landscape. Two or three hard-edged horizontal colour zones dominate: a vast heavy upper zone for 100% cloud cover, a soft grey-green lower field for 17.2 C, and one darker storm-pressure band hinting at today's thunderstorm outlook. Almost invisible graph-paper grid beneath the colour, slight horizontal squeegee drag, fine rain grain with a southerly lean from 8.8 km/h wind at 189 degrees; add one controlled diagonal overprint tear only for the thunderstorm forecast, not a dramatic sky. One crisp full-width bright amber #fbbf24 datum line sits in the just below the middle for 1002.1 hPa pressure. Bright amber ATMOSPHAERE label upper left with a thin pointer line; near-black lower-left data panel with amber monospace text: NOW 17.2 C / RH 86% / 1002.1 hPa / WIND 8.8 km/h 189 deg / slight rain / rain 0.0 mm / OUTLOOK H 19.2 C L 16.7 C thunderstorm rain 95% 13.1 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.
