Dormant mecha robot lock-screen wallpaper, Seedream 5.0 Pro

Retro 80s anime cel illustration with airbrushed gradients and film grain. Minimalist lock screen composition: a colossal battle-worn mecha robot kneeling dormant in an overgrown field, placed entirely in the bottom third of the frame, moss and vines on its rusted armor, one faint red eye sensor still glowing. The upper two thirds are a vast empty pale morning sky in soft warm grey and cream gradient with thin haze, immense calm negative space. Melancholic post-war quiet. Full-bleed vertical mobile wallpaper, image extends seamlessly edge to edge, no border, no frame, no margin, no phone mockup. Generic original mecha design, no text, no logos, no watermarks, completely unbranded.
