Banner 13 block design & features
Banner13 is a full-width bordered offer bar built with shadcn/ui Button, pairing a live monospace countdown pill with muted promotional copy and a rounded outline claim action. On small screens the pill, sentence, and button stack; on wider screens they sit in one max-width row.
The countdown chip uses a muted pill shell, hairline border, and a small destructive status dot for urgency, while the surrounding bar stays on the page background with a bottom border only. The timer ticks every second down to days, hours, minutes, and seconds against an endsAt timestamp (or a demo window from first mount).
The mood is time-sensitive retail without heavy decoration - a common launch-pricing pattern with a sharper edge from the live countdown. Complexity is low: supply an end date, offer line, and CTA URL.
