in case you missed it: yesterday i wrote about a new open source tool i made, called RSC Explorer.
it lets you interactively step through how the React Server Components protocol works directly in the browser — no server needed.

✨ I just published a new post, and it’s all about one of the most mind-blowing new CSS features: subgrid.
Honestly, when I first heard about subgrid, I figured it’d be a convenient little utility. I had no idea it would solve one of the most longstanding issues I’ve had with CSS. 😮

aargh someone kill me. literally THE WHOLE POINT of directives is that they’re not just strings!
they’re syntactically attached to the scope (function or module) in a way that’s reflected in AST.
and both RSC and Next.js ones act at module boundary which is kinda gross for decorators or API calls
