Programming5 minVeltrix Was Killing Us With YAML
The Problem We Were Actually Solving The real pain wasnt disk size; it was cognitive load on level designers. Every hunt lived in a separate fork of the same monorepo, diffing 14 kB YAMLs was misery, and once the file exceeded 100 kB we started getting partial-checkout timeouts in CI because Git...

I've integrated a lot of data grids over the years. Every time, the experience was the same — open the docs, search for the prop I need, find three different ways to do the same thing, pick one, get it wrong, Google it, eventually get it working, and forget how I did it by the next...
