“16”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; dark athletic fabric weave as background — close-up textile surface texture, matte finish, no shine. Background: deep navy polyester mesh fabric surface filling the entire square frame — pro jersey material, fine hexagonal weave visible in overhead studio light, matte non-reflective athletic textile. Single controlled studio light from above-left: fabric weave catches the light creating subtle sheen without gloss. "16" as massive ultra-condensed block numerals filling at least 80% of the canvas width — letterforms extending nearly to the left and right frame edges, almost touching. The number reads with absolute authority: this is the jersey number, nothing else.
