参考上传的图片，Design a minimali

参考上传的图片，Design a minimalist black-and-white logo for “Dolphin Esports”.The logo must prioritize overall stability and be formed by one single, complete, closed outer shape.Use only one negative space cut to subtly suggest a dolphin and sensory perception (sonar / awareness), without depicting a full dolphin silhouette, eyes, waves, speed lines, or multiple geometric elements.The design should feel rational, calm, restrained, and long-lasting, avoiding aggression, motion, sharp angles, or fragmented forms.The logo should function as a timeless brand symbol, not an illustrative or action-based icon.It must work perfectly in pure black-and-white, remaining clear and stable at very small sizes.Follow an extreme reduction philosophy: less is more, never fragmented.
