The official documentation around WordPress’s Gutenberg block system (especially in the full site editing context) sucks. The best way I found to get close to understanding the potential valid properties was to parse the WordPress GitHub.

I got tired of reverse engineering block structures just to build custom themes and blocks, so I built this. A searchable, structured doc site focused specifically on block-level markup and patterns.
