Golden Age Locomotive

Prompt

A vintage steam train in 9:16 vertical focus. The train is green enamel with gold leaf detailing, positioned in the bottom half moving along tracks. The upper third is a vast, clear, brilliant blue sky with no clouds, providing high legibility for status icons. Large wheels with visible spoke detail in the foreground. Minimalist composition. No watermark, no logo, no signature, no text, no UI, no mobile screen, no device frames, no interface elements, no artifacts, no borders, no margins, no cropping, no cut-off parts.
