          Description: GenAI-native pixel art format and compiler
           Pixelsrc (pxl) is a GenAI-native pixel art format that enables
           creating and manipulating pixel art through a declarative syntax.
           It supports palettes, layers, animations, and compositions with
           a focus on AI-assisted workflows.
