Cyberpunk Runway Fashion Poster

Generate an avant-garde runway-show-style visual poster: black background, oversized white thin sans-serif English lettering, with the type boldly cropped by the canvas edges to create a strong, modern-magazine layout feel, at a 9:16 ratio. In the center of the image, place a close-up of the face or eyes of {argument name="character" default="Viper from Valorant"}, rendered in high-contrast neon duotone. The colors should automatically adapt to match the character. Overall, it should have an electronic neon glow in cyan, magenta, blue-violet, red, and similar tones. Add grain texture, poster-style shadows, intense lighting and shadow, and a nightclub / fashion-show feel. The large title text overlaps with the character image, in an asymmetrical layout. Add a small amount of fine-print information, such as {argument name="location" default="Tokyo"}, {argument name="time" default="22:00"}, the date, and a subtitle. Square poster composition, with a premium, high-fashion event-poster quality.
