Create a finished 3:4 portrait sports number poster in strict black and white. Render only these exact text strings, with clean spelling and no extra lettering: top eyebrow “VARSITY ATHLETICS”; dominant headline “249”; bottom detail “JERSEY NUMBER · 249”. Make “249” the unmistakable focal point, occupying roughly 60% of the canvas width. Build its letterforms in bold, wide Varsity Block collegiate construction with softly rounded corners, generous proportions, a solid black interior, a thick crisp white outer border, and a second white inner keyline creating the classic channel effect. Keep the white borders clearly visible against both the lettering and background; add fine white screen-print halftone dots and slight ink edge bleed without making the numerals fuzzy. Place the small uppercase eyebrow centered near the top, the giant “249” centered across the middle, and the compact bottom detail centered near the lower edge. Behind the number, show a generic sprinter leaning forward mid-stride, cropped by the numerals and softened with directional motion blur; keep the figure subordinate and monochrome. Use a near-black stadium void with faint floodlight haze, a hard upper-left white rim light tracing the numeral edges, deep opposite-side shadows, and narrow white speed lines radiating outward behind the headline without crossing or obscuring the lettering. Add restrained jersey-print grain and halftone texture; ink sits on the surface and does not glow. High-contrast athletic outdoor lighting, sharp graphic edges, screen-print texture, dramatic rim lighting, layered poster composition, polished high-resolution render. No color accents, no logos, no extra words, no decorative stars, no gradients that introduce color.
