How to use: the promo plays on a loop with an original mbira-style soundtrack (click anywhere once to enable sound). Click Export MP4 (or WebM) to record one full pass — soundtrack included — and download core-africa-group-promo.mp4 (1920×1080, ~70 s), ready for WhatsApp, LinkedIn, Facebook or YouTube. MP4 export needs a recent Chrome or Edge; if the MP4 button is greyed out, export WebM instead (also accepted by most platforms).
