A single glossy 3D coin caught mid-flip in the air, slightly tilted, with a soft faint curved motion arc behind it, one face engraved with a glowing golden sun, the other with a glowing silver crescent moon, smooth metallic-gloss highlights, a few tiny four-point sparkles around it, set on a deep violet to soft lavender vertical gradient background. Soft 3D render in the style of a premium polished mobile-app icon, smooth glossy material with a soft satin finish, subtle subsurface sheen and crisp fresnel highlights, plump rounded dimensional forms, clean soft studio lighting with a soft long contact shadow beneath the subject, gentle glow, very clean and uncluttered with generous negative space, the top portion kept clear and empty (smooth gradient only) reserved for a title, focal subject centered in the lower two-thirds, square tile with softly rounded corners, high detail, ultra-clean polished finish, dreamy mystical premium aesthetic, no text, no letters.
