Umberspark

App icon: an abstract shape brand mark called Umberspark — pure geometric identity. Centered glyph: a small sparkle with 1 large satellite glint, rendered in #f5f5f5. flat vector style, radial gradient background glowing from #404040 at the center out to #171717 at the edges. Details: a flat 45-degree long shadow cast by the glyph. Requirements: square 1:1 canvas at 1024×1024, full-bleed background with no transparency, no text or wordmarks, no baked-in rounded corners or borders (the OS applies its own mask), glyph optically centered and contained within the central 66% safe zone so it survives the iOS squircle and Android circular launcher masks, crisp anti-aliased edges, high detail, professional app-store quality.
