3D icon of a stylized, glowing letter "S" curved with a fiery trail following its path. The letter "S" should be a vibrant, bright white at its core, transitioning smoothly into vivid yellow and deep red hues along the edges, mimicking the appearance of a blazing flame or hot metal. The fiery trail should glow intensely with red and orange shades, fading smoothly into the background, and follow the natural curvature of the "S" to give it a sense of dynamic motion. The surface of the letter should have a smooth, glossy texture with subtle material shading that enhances the effect of glowing hot metal, giving importance to gradients and light reflection. The lighting should come from an upper-left direction, highlighting the "S" to emphasize its 3D form, with gentle highlights and avoiding harsh shadows. white background, centered, no shadow, clean icon style, high detail, 3D render.
