Minimal app icon logo for an AI aggregator brand "Mevali": a bold geometric letter "M" formed by three separate rounded lines (streams) that converge and merge into a single point at the bottom center, symbolizing many AI models combined into one. Bright lime green #CAFF00 symbol on a near-black rounded-square background #0B0B0C. Flat vector, thick consistent stroke, no gradients, no text, no mockup, centered, iOS app icon style.
