Based on the provided white-background product images, generate a detail page poster for the commuter half helmet. The background is a soft beige to warm white gradient, with a bright yellow rounded information bar placed horizontally at the top, featuring a simple linear safety icon and a short phrase reading "Daily Commuting / Comfort Protection." The upper left uses a black thick sans-serif line titled "Light Escort / Safe Departure," with a line below explaining "Rounded shell and clear face shield, suitable for city riding." The central section enlarges a white half-helmet, with the transparent mask lowered, revealing the black lining, chin strap, and red buckle fully visible. At the bottom, there are four uniform-width light beige rounded small cards, sequentially showing partial material or component diagrams for "soft lining," "clear mask," "streamlined ventilation," and "secure buckle strap," with only one short label per card. Maintain the smooth white shell, transparent mask, and black strap, with adjustable vents, mask curvature, and small card details. The product body originally had no brand information, and no new brand, slogan, certification mark, or logo were added. Avoid original image brand, sales ranking, national standard number, specific certificates, fine footnotes, and watermarks.
