A haute couture showcase at the Mulungushi Conference Centre, selling its own tickets. The site has to do two jobs that pull against each other: feel like the event, and take money without friction.
The design commits rather than hedges — deep olive, gold, enormous letter-spacing, and nothing on the page competing with the two buttons that matter. No carousel, no stock photography, no popup asking for an email before you have seen anything.
It takes real money. Mobile money on Airtel and MTN through a Zambian gateway — initiating the collection, verifying the signed webhooks that come back, and reconciling the gateway's view of a payment against our own. That last part is where payment integrations usually go wrong, and it is most of the work.
This one will not render in a frame the way the two above do: the site sends an X-Frame-Options header refusing to be embedded anywhere. That is the correct setting for a site handling checkout, so what you see here is a screenshot and the link opens the real thing.
