Banner 18 block design & features
Banner18 is a full-width promo bar built with Shadcn UI Button. A primary tag icon leads into discount copy, a dashed mono code chip with copy/check feedback, and a pill redeem control aligned to the end of the row on wider screens.
Color stays theme-neutral: background fill, muted chip surface, and primary accents on the icon and hover states. Density is tight with modest vertical padding and a single horizontal content band. The only motion is the icon swap after a successful clipboard write.
This reads as a straightforward commerce promotion pattern rather than a decorative marketing flourish. Complexity stays simple and content-driven: title, supporting line, promo string, and CTA label.
