{"id":"36591","prompt":"Create a 4:5 vertical professional cycling helmet promotional poster, with the core composition being \"Airflow Profile Gates.\" A structurally realistic road cycling helmet is suspended in the center at a side two-thirds angle, with a matte ivory white shell; internal EPS cushioning and black webbing are naturally visible only at the vents. Three evenly spaced thin rectangular wind tunnel gate frames stand vertically in front of the helmet, and two narrower frames stand behind, creating clear foreground and background space.\n\nFour semi-transparent cobalt blue airflow bands with real volume enter from the left, passing through the front gate frames and helmet vents; each band is compressed and split in different channels, then re-merges into two smooth wakes behind. The airflow bands cannot pass through the solid shell nor become glowing neon lines. The gate frames have a light gray metal surface with extremely thin fluorescent orange edges at the cross-sections to emphasize airflow entry and exit points.\n\nThe title \"AERO\" is placed vertically on the far right with large spacing between letters; two wake streams pass through the negative space between letters without obscuring readability. Only \"VENT 18 / ROAD HELMET\" is kept in the bottom left corner. The background is a clean cool gray studio, with soft shadows on the ground formed by the helmet, gate frames, and airflow.\n\nCombine high-speed product photography with engineering aesthetics, emphasizing real shell curvature, vent channels, and airflow logic. Full opaque rectangular background, no transparent corners, no Alpha masks, no edge feathering. No riders, no bicycles, no exploded views, no HUD parameters, no cyberpunk, no existing brand logos, no watermarks.","promptEn":"Create a 4:5 vertical professional cycling helmet promotional poster, with the core composition being \"Airflow Profile Gates.\" A structurally realistic road cycling helmet is suspended in the center at a side two-thirds angle, with a matte ivory white shell; internal EPS cushioning and black webbing are naturally visible only at the vents.
