A self-contained neo-brutalist theme preset — a flat white card with hard 3px black borders, a solid blur-free offset drop-shadow, chunky mono type, a loud accent block, a stat, a rotated corner sticker, and two buttons. Interactive blocks do the classic brutalist nudge toward their shadow on hover and press. A keyboard-operable radiogroup of accent swatches re-tokens the whole panel live; the palette is fully exposed via presets and colors. Pure CSS — reduced motion pins every block to its raised resting pose.
