“01”是使用 FontVibe AI 创作的运动风文字效果。粗重窄长的铬金属大写字母带丝网印刷颗粒，红蓝轮廓光勾边，背后一个运动员剪影冲破速度线。

screen-printing ink texture — slight edge bleed at letter borders, fine halftone grain on ink surfaces, ink sits on top of material rather than glowing through it; strong side rim light from upper-left casting sharp bright outline along letter edges, deep shadow on opposite side, high-contrast athletic outdoor light quality; faint speed lines radiating outward from behind the text, suggesting kinetic force and forward momentum; deep dark background — rich black or near-black, allowing the letter treatment to dominate without competing texture. "01" rendered as oversized opaque white screen-print ink on the back of a black technical-mesh football jersey, ink visibly raised above the fabric with faint edge bleed, fine halftone grain, tiny pinhole imperfections, and subtle woven polyester texture visible around the numeral edges. A lone athlete silhouette is captured from behind in a forward-driving sprint, shoulders and arms blurred into directional motion while the printed "01" remains crisp and dominant. Strong upper-left stadium floodlight creates a sharp icy-white rim along the jersey seams and numeral edges, with dense blue-black shadow falling across the opposite side. Deep near-black athletic arena background, sparse rows of crowd lights dissolved into defocused bokeh. Thin pale speed lines and fragmented screen-print streaks burst outward behind the athlete without crossing the numeral. Flecks of turf rubber and dust hang in the air, frozen by high-shutter sports photography lighting. High contrast, black, white, steel-blue, and restrained electric cyan accents; tactile ink-on-fabric finish, cinematic stadium darkness, sharp foreground detail, shallow depth of field, realistic sports campaign image.
