Create a print-ready back-of-youth-sports-shirt personalization composition, portrait 3:4. Render only two text elements, centered with generous clear space: top name "RIVERA" and oversized number "10" beneath. The name spans the upper shoulder line in compact, hand-drawn ultra-condensed black athletic capitals, tall letterforms with extreme heavy strokes, flat-cut terminals, tight but legible tracking; each letter is individually built for clean heat-transfer vinyl cutting. Set "10" at 4 times the name height: towering ultra-condensed black digits, near-solid heavy forms, minimal counters, flat-cut terminals, precisely centered. Use a single solid ink color: deep black #0A0A0A. No gradients, shadows, distressing, outlines, highlights, textures, logos, team crests, player image, extra copy, or background graphic. Present the lettering as a clean vector-like preview on the back panel of a plain white child-size short-sleeve jersey, straight-on view, smooth matte polyester fabric, seams faintly visible, neutral pale-gray studio backdrop. The lettering must be razor-sharp, correctly spelled, and fully readable.
