Tailwind CSS v4 đã ra mắt với nhiều thay đổi lớn: không còn bắt buộc file `tailwind.config.js`, cấu hình trực tiếp trong CSS bằng `@theme`, và tích hợp sẵn container queries, 3D transforms. Sử dụng CSS variables thay vì `@apply` được khuyến khích. Build nhanh hơn với Oxide engine. Dễ dàng nâng cấp dần từ v3.

Why "developer-first"?
Because feedback should flow directly into your workflow. Not force you into a new tool with its own UI, notifications, and mental overhead.
Widget or SDK → Your dashboard → GitHub issue. Done.

react top down tree reactivity is crippling..
one thing i often need to have is a protocol between parent and child, so that both can agree on something. yet i don't want the child view to encode that.. which mean i need to lift the state out and bind logic to this.. am i writing smalltalk by then ?
seems like stores don't solve that either unless every component comes with a store (which bring back objects protocols again)
