A cinematic, premium photographic scene for a mobile-first student marketplace hero. A young diverse University of Lusaka student, seen from a natural over-the-shoulder angle, holding a sleek smartphone displaying a vertical TikTok-style product reels feed with clean product cards. Warm late-afternoon campus light, softly blurred modern campus architecture and greenery in the background. Sophisticated, energetic, trustworthy mood, shallow depth of field, dark moody tones with teal-blue ambience, high contrast, photographic realism. No visible readable text on screen.
