Design a premium music control UI overlay for a 1280x720 video (Adobe After Effects), inspired by Apple Music and iOS design language. Requirements: Layout Bottom-centered horizontal control bar Perfectly symmetrical alignment Generous padding and spacing (Apple-style precision) Background Frosted glass (glassmorphism) Semi-transparent dark layer with strong Gaussian blur Subtle inner glow + soft edge highlights Very slight gradient (dark gray → near black) Controls Three icons centered: Previous (left) Play/Pause (center, ~20–30% larger) Next (right) Icons must be ultra-clean SF Symbols–style (thin, geometric, perfectly balanced) Color: Pure white (#FFFFFF) at ~85–95% opacity Micro-details Soft outer glow for icons (very subtle) Gentle drop shadow under the bar for depth Pixel-perfect spacing and alignment Slight rounded corners on container (modern iOS style) Interaction feel (visual hint) Center button slightly emphasized (scale or brightness) Suggest tactile feedback (like iOS buttons), but no actual animation needed Style constraints No text No clutter No bright colors No skeuomorphic or heavy effects Must feel premium, minimal, and high-end Output Transparent PNG (UI only, no background)
