16:9 aspect ratio, widescreen, cinematic. A hyper-minimalist digital command interface. The entire frame is a deep, pure matte-black void (#000000). Occupying the background is a flawless, ultra-sharp vertical stream of electric green (#00FF00) monospace code and transaction hashes scrolling at high velocity. Centered perfectly in the foreground is a sharp, stark white rectangular block. Inside the white block, the text [ SYSTEM_ACTIVE ] is rendered in a bold, black, professional sans-serif font. The composition is brutalist, balanced, and perfectly flat. 8K resolution, pixel-perfect detail.
