Stylized glossy elemental orbs (yellow, red, green, blue), clean 2D game icon style, similar to casual mobile slot icons. Perfect round shape, centered, no background clutter. Strong glossy highlights, smooth gradients, vibrant colors, soft glowing aura around each orb. Inside each orb: subtle simplified radial pattern inspired by the sun — soft curved rays or swirl lines, minimalistic, semi-transparent, blended into the surface (not sharp, not detailed). The pattern should feel like energy inside the orb, not a texture on top. Add small light streaks / energy arcs wrapping around the orb. Clean vector-like rendering, high readability, no noise, no texture grain. Style: semi-flat with soft glow + slight gloss, similar to modern casual game UI (Playrix / match-3 style). No outlines or very thin outline only.
