Field Reading, a Bureau meteorological instrument print, 4:5 portrait. Two hard-edged horizontal zones dominate: a vast soft grey-green upper zone for clear 18°C air, a restrained warm ochre lower undertone anticipating a partly cloudy 23°C afternoon; faint graph-paper grid and subtle near-vertical squeegee drag, analogue tube-amp warmth, not a painting. One crisp full-width bright amber #fbbf24 pressure-isobar datum line at mid-height, near-black border, registration crosses. Upper left readable small caps ATMOSPHAERE with thin amber pointer. Lower-left weighted near-black monospace panel in amber: NOW 18.0C / RH 71% / 1017 hPa / W 5.1 km/h / CLEAR; OUTLOOK H 23C L 14.3C / PARTLY CLOUDY / RAIN 0%; outlook dimmer. One small mis-struck amber Bureau seal lower right. No figures, skyline, landscape, photograph, soft gradients, or decorative neon. Output in exactly 1122 x 1402 px, 4:5 portrait ratio.
