Pixel Art Upscaler & Palette Quantizer Tool CLI

Nearest-neighbor integer scaling, edge-preserving upscaling, and retro palette color reduction CLI.

High-precision pixel art upscaler and color quantization CLI utility. Designed to upscale low-resolution retro sprites (16x16, 32x32, 64x64) to crisp 4K and 8K presentation assets using exact integer nearest-neighbor sampling with zero blur, coupled with a median-cut and k-means color quantizer to enforce authentic retro console palettes (PICO-8, Game Boy, NES, Commodore 64).
