Pilates — pure-TypeScript layout engine inspired by Ink's space

[zhijiewong]

Hi Vadim and Ink community,

Heads-up that I've published Pilates 2.0 this week — a pure-TypeScript flex layout engine validated cell-for-cell against
Yoga across 33 oracle fixtures and a structural-differential fuzzer. It's positioned as an unbundled alternative to the
Ink+Yoga stack rather than a drop-in Ink replacement; lots of folks still ship production CLIs on Ink and that's the right
call.

You might find the structural-mutation result interesting: across the 9 scenarios in my bench suite, the pure-TS engine
runs ahead of WASM Yoga on each — including the structural-mutation workload (append + remove a row per frame) Yoga led on
by ~5× until last week. That flipped to a ~1.7× Pilates win once I replaced the cumulative-sum main-axis position rule with
a linear recurrence and folded default-valued style inputs out of the grammar.

Not asking for anything — just a courtesy note since the project sits in territory you've shaped for years. Repo:
https://github.com/pilatesjs/pilates

Happy to chat about layout semantics, fuzzer setup, or the algorithm changes if it's useful to you. Either way: thanks for
Ink, it set the bar I was aiming at.
