ZJIT is now as fast as YJIT
After some infrastructure deployment shenanigans, we deployed some regions of storefront renderer (SFR) running on ZJIT. We have seen some promising numbers.

I'm very excited to announce Halfspace, my experimental cross-platform IDE for solid modeling with distance fields!
This has been in progress since midway through last year, and it's finally "done enough" to make it more public.
