A bold vector illustration of the U.S. Capitol Building dome rendered in clean white and light-grey flat shading with thick black architectural outlines, columns and windows clearly detailed. Behind the dome, multiple fireworks burst in red, white, and blue brushstroke trails filling the sky with sparkle accents. A small American flag waves atop the dome's peak. Soft star confetti scatters across the upper composition. Thick black outlines anchor the entire structure crisply. Background is a smooth, solid warm cream-beige (#EADBC7), clean and minimal, no texture. Patriotic Americana civic theme, crisp vector linework, premium high-resolution wallpaper quality, vertical composition.
