Neon Pixel Relic

Create an image inspired by 1980s-1990s digital graphics, as if it were produced on early systems like MS-DOS, Windows 3.1. Break down all visual elements into simple, blocky, pixel-based shapes, using a limited palette of 4-16 vibrant colors. Replace complex gradients with flat colors or basic two-tone transitions.
The image should feature visible pixel structure, including an RGB subpixel grid, horizontal scanlines, slight chromatic fringing on edges, and soft glow around brighter areas.
Use a 100% black background with subtle digital noise. Colors should appear self-illuminated, with gentle light bloom and slight color bleeding into darker regions. Add light surface artifacts such as moiré patterns and floating dust.
Keep the composition centered, with the main subject filling around 60-70% of the frame. Emphasize the pixel grid with sharp detail, while applying a subtle vignette that darkens the edges.
The overall look should feel like authentic early computer graphics chunky, low-resolution, and unrefined. Avoid any modern rendering or references to physical screens or devices; the image should exist as a purely digital object floating in darkness.
