Design an original tech brand logo icon for “ITOSTAR / 优化之星”, inspired by a modern Google-like multicolor geometric icon language, but clearly original and not مشابه any existing brand logo. Create a custom rounded star outline, not a standard five-point star, using clean monoline strokes with consistent stroke width, soft rounded corners, flat vector style, minimal, modern, professional, friendly, stable. At the center, add a small hollow four-point sparkle cutout, elegant and subtle, not a medical cross. Replace part of the lower-right outline with 2 to 3 short rounded dashed segments, suggesting optimization, acceleration, and digital tuning. Add a small signal element on the upper-right side: one dot plus two rounded signal arcs, representing mobile consulting, tech trends, and information connection. Use flowing segmented multicolor distribution along the stroke path, inspired by Google-style color harmony: blue, green, yellow, and red, with blue and green dominant, yellow and red as accents. Keep it flat, vector-like, clean, balanced, iconic, highly recognizable, suitable for website header, social media avatar, favicon, and app icon. White or transparent background, no mockup, no text, no 3D, no metallic effect, no shadows, no perspective, no clutter.
