A single oversized punctuation glyph stands centered in a vast, near-empty retro video-game title screen, floating in a deep matte-black void that recedes into soft charcoal gradients toward the edges. Faint horizontal scanlines and a subtle low-opacity pixel-grid texture stretch across the background, evoking an old CRT display, with a faint dark vignette pulling focus inward. A soft cool cyan-to-violet ambient glow washes up from the lower third of the frame like distant stage light, catching the ground plane in a faint reflective sheen made of tiny dithered pixel dots, without ever touching or tinting the glyph itself. Sparse floating square particles, matching the pixel scale of the type, drift loosely in the upper corners for depth, sized clearly smaller than the glyph so they never compete with it. The single glyph sits dead-center, large and dominant, occupying roughly half the vertical frame height, surrounded by generous flat black negative space above and below to let it breathe like a hero logo mark. No additional text, no ground horizon line detail, no extraneous graphic elements — just the glyph, the dark atmospheric void, and quiet ambient light framing it like a stylized retro game boot-up screen.
