A futuristic rectangular sci-fi label frame with clearly rounded corners, designed as an isolated UI element. Wide horizontal aspect ratio with a large completely empty transparent center, intended for adding text later. The frame itself is highly detailed, with intricate futuristic circuitry, micro-electronic components, segmented metallic structures, thin luminous lines and subtle geometric technology patterns integrated into the border. Rounded outer corners with smooth, sophisticated curvature, while the inner corners are also rounded and follow the same geometry. Dark graphite, brushed titanium and subtle emerald-green/cyan luminous accents. Premium futuristic spacecraft interface aesthetic, elegant high-tech design, precise hard-surface 3D construction, subtle depth and metallic reflections. The entire area INSIDE the rounded rectangular frame must be fully transparent, including the center. The area OUTSIDE the frame must also be fully transparent. Only the actual decorative border is opaque. No dark panel, no glass panel, no solid fill behind the frame. Perfectly front-facing, symmetrical, centered, clean rectangular composition. No text, no letters, no numbers, no symbols, no logo, no objects inside the frame. Transparent background with true alpha channel, isolated border element, crisp clean edges, no background, no floor, no environment, no cast shadow, no vignette.
