关于这个设计

One flat chest graphic: a bold retro megaphone tilted upward with three thick sound lines and small stars bursting out. Stacked headline in very large extra-bold condensed caps, sky blue with a golden outline: "LOUDEST GRANDMA" on the first line, "IN THE STANDS" slightly smaller on the second. Below the megaphone two triangular pennant flags on short poles, one coral and one aqua, carrying the names "LEO" and "RUBY" in huge thick cream caps filling each flag. Text, each spelled correctly and appearing exactly once: "LOUDEST GRANDMA", "IN THE STANDS", "LEO", "RUBY". Style: sporty retro flat-vector, thick outlines, sky blue, coral, aqua and golden palette. On the black shirt, no pure white anywhere — all light strokes and fills are warm cream, high contrast, print-ready.
