Elite Performance Running Shorts: Dynamic Coastal Campaign

Use the uploaded image as the exact product reference if supplied; otherwise create lightweight split-hem running shorts for fictional women's performance label Nera Run. Preserve the referenced shorts precisely including waistband, drawcord, hem shape, side splits, liner visibility, logo, fabric, color, stitching, and proportions. Capture an adult female runner in a powerful mid-stride sprint along a clean coastal promenade, front leg reaching naturally and arms positioned in authentic running form. Styling should communicate strength, confidence, feminine athletic fashion, and premium performance. Background features modern coastal architecture and distant ocean with controlled blur. Use sunrise backlight combined with subtle frontal reflector fill, producing glowing rim light while keeping product details crisp. Low three-quarter action composition, frozen garment movement, realistic anatomy and running mechanics, no exaggerated body proportions, no watermark, no unwanted text, ultra-realistic high-speed 8K campaign photography, aspect ratio 16:9.
