Build an event hero with Tailwind CSS: the event name as the headline, a line with date, time and venue, and a countdown block showing days, hours, minutes and seconds to the start in four monospace cells. Add a register button with remaining-seats scarcity ('42 of 200 left'), a subtle animated background in the brand palette, and an 'Add to calendar' link beside the CTA.
