A cinematic presentation background, 16:9 aspect ratio. Dark purple and deep blue gradient backdrop (#1a1a2e to #16213e). In the foreground, a translucent floating smartphone interface showing abstract emotion waves and data curves in soft orange and cyan. On the right side, subtle silhouettes of two teenagers sitting side by side but separated by a faint transparent glass wall. Warm amber accent light (#e94560) glowing from the gap between them, symbolizing genuine human connection. Minimalist, clean, no text, no logos, soft focus, suitable for a presentation title slide. High quality, 4K.
