Create a production-ready die-cut number decal on a clean square presentation sheet. The only rendered text is "17m". Center it large, occupying 78% of the canvas width, with generous clear negative space around the silhouette; no extra words, logos, numbers, or background typography. Design "17m" as custom collegiate athletic lettering: broad upright block construction, slightly softened outside corners, wide squared counters, thick deep-red outer outline, narrow white keyline channel, and an inner championship-gold pinstripe following every contour. The "17" is massive and dominant; the lowercase "m" is compact but built from the same block geometry, baseline-aligned to form one unified racing number mark. Add tiny white five-point star insets only at the upper stroke junctions of the 1 and m, integrated into the lettering rather than floating. Fill the letters with dark carbon-black textured enamel, subtle diagonal weave visible only inside the fill. Apply a hard overhead studio light: sharp white specular strips along the top-facing red edges, crisp charcoal extrusion shadow directly down-right, restrained red reflected glow. Present as a premium vinyl decal with clean die-cut perimeter, smooth satin surface, no wrinkles. Background is matte near-black track asphalt with a barely visible curved white lane marking at the bottom edge, sparse horizontal white speed streaks extending left from the lettering and dissolving into darkness. Square frontal composition, high-resolution product key art, precise vector-clean contours, no people, no vehicles, no illegible text.
