霧の格納庫に跪く巨大装甲メカの壁紙

Vertical 9:16 phone wallpaper of a towering armored mech kneeling in a misty hangar, a glowing energy core pulsing in its chest, heavy weathered steel plating and hydraulic detail, soft industrial light and drifting fog, the giant low with tall dark space above, steel grey and amber palette, imposing solemn mood, no text, no logo, no watermark, no borders.
