Vertical 9:16. One continuous five-second photorealistic shot. Natural stable anatomy, consistent identity, clothing and object shapes throughout. Gentle believable motion only. Clean premium composition, no cuts, no text, no logos, no captions, no dialogue. The selected clearly adult woman age 28 wears a modest coral athletic top, charcoal full leggings and white trainers in a bright fitness studio. Full-body front view, she shifts her weight once and gently turns her head toward camera. Both feet stay planted and visible, arms relaxed, no provocative posing or body changes.
