Mindnest logo with clever negative-space brain-nest icon and clean typography

Design a minimal, clever, and professional logo for a fictional company named "Mindnest". It's a virtual business that provides online learning, creative thinking workshops, and digital brain-training tools. The logo must include a smartly crafted icon that uses negative space to subtly represent either a brain, nest, or abstract “thought” symbol. The icon should be integrated with or positioned near the brand name “Mindnest”, using clean typography that complements the minimalist aesthetic. Avoid clutter—let the negative space be the hero, creating a visual “aha!” moment. The logo should look great in both dark and light themes and be easily recognizable at small sizes. This is a test logo, but design it as if it were for a real, creative ed-tech startup.
