Create one production-ready macOS application icon for Cortala, a voice dictation, translation and voice commands app by CortexKinematics. Square 1024x1024 composition. A clean rounded-square app tile on truly transparent outer corners. Tile background: luminous rich cobalt blue to indigo gradient (#3867ed to #4f46e5), matching the parent brand's blue/indigo palette. Center a single bold pearly white sculptural speech waveform monogram loosely suggesting a C, with three softly rounded vertical voice bars integrated into an open circular C shape. Minimal, geometric, excellent legibility at 32 pixels. Refined restrained macOS material shading, subtle depth and crisp edges. Generous margin, balanced silhouette. Professional and friendly, a sibling to a blue/indigo robotics/automation brand. No text, no wordmark, no letters other than the implied C shape, no green, no black background, no microphone clip art, no extra symbols, no mockup, no canvas border. Return the icon asset alone.
