+Use case: logo-brand. Generate ONE finished app icon for PhotoLive, a professional enterprise event photography and live photo sharing app. Output EXACTLY 1024 by 1024 pixels, square PNG. Full-bleed solid brilliant blue background #1A73E8 extending to all four square edges, opaque background, NO pre-rounded outer icon corners. In the center a beautifully balanced distinctive white geometric camera aperture symbol, six broad expertly spaced interlocking shutter blades encircling a clear blue hexagonal lens opening. Subtly integrate the silhouette of a photographic frame into the overall mark without additional separate symbols. Strong simple memorable silhouette, highly legible at 48px, flat vector-like precision, smooth optically corrected curves, generous safe area of about 20 percent around the central symbol. White mark approximately 60 percent of canvas width. Premium calm modern visual identity consistent with blue-and-white PhotoLive admin and mobile UI. Pure flat colors blue and white, no gradients, no shadows, no 3D, no glossy highlights. No text, no letters, no wordmark, no Chinese characters, no slogan, no watermark, no presentation board, no mockup phone, no multiple alternatives. This is the actual exportable icon asset, not a picture of an icon on a background.
