Midjourney prompt: A minimalist logo for 'La Voie du Cœur Unifié' featuring a harmonious circular design with a stylized heart symbol at the center. The design incorporates soft, flowing lines and natural elements such as leaves or gentle waves to evoke compassion, unity, and self-care. Use an earthy color palette with sage green, soft blue, and warm peach tones. The logo should feel tranquil, authentic, and balanced, with clean and elegant lines, without any text."
