What I learned designing a barebones UI engine
Summary
A developer documents building a minimal PyGame UI engine from scratch, detailing architecture choices from a flat hit-test loop to a depth-first, tree-based layout. It covers asynchronous support, global event listeners, and performance optimizations, and outlines future directions like declarative APIs, composability, and a styling system. The post serves as a practical case study in lightweight UI tooling for experimentation.
