@JasonTheAdams Thanks! LGTM, only I'd suggest keeping a link to PSR-12 for easy referencing.

The PER Coding Style is the successor and extension of PSR-12. As such, we should be encouraging folks to use that standard. Some IDEs support it, and the AI agents will know what to do with it. Unfortunately, PHPCS doesn't yet support it. The good news is that if someone is using PER then PHPCS will not flag anything as incorrect, as it simply doesn't cover the areas that PER does, but PER covers everything PSR-12 did.
I didn't want to get full into this in the doc, but wanted to at least mention and address that PER is the intended standard.
