Firstly, that Doom project with types is incredible, but reading about typescript itself from Axel is also good. There are also updates from Astro v5.4, Svelvet, and Lynx. Josh created whimsical animations and interesting posts about CSS functions, fluid typography, accessibility considerations, and completely random check inconvenient objects. Happy Reading!
I noticed this last week, but if you somehow missed that, then definitely check it out. Dimitri Mitropoulos decided to run a doom engine entirely written in TypeScript types. This project only needs 177TB of TypeScript types to be rendered over a 12-day period and will render the first frame of the game. Probably, the word "only" is an understatement.

This is insane, amazing and crazy at the same time. In any case, when somebody complains about complicated types in a project, show them this video:

This post explains the maintainers' dilemma when they decide what will be merged and what is important. It's a really good read.

Josh Comeau is in the process of creating a new course, this time covering animations. Josh, being Josh, had to make it with wow effects, and I think he managed that with flying colours (pun intended). Check that page and play with the settings (Chaos toolbar) in the top right corner. It's probably not useful, but there are definitely a lot of things on one page.

Here is an explanation of some of the secrets: https://www.joshwcomeau.com/blog/whimsical-animations/
Once this is supported, I believe it will completely change how we write CSS. Imagine Functions that have types, returns, lists, and all of that in CSS. Also, the post has a few good examples to give you a quick overview.

It’s a very interesting idea to put a clamp() on HTML tag. Also, the hardest bit is to stop that
16px == 1rem conversion, because, well, it is not.

You can build accordion-type content simply using
<details name="story">content</details> , however, there is an issue if there is loads of content the browser will lose last scroll position. With a bit of JavaScript that is sorted too.
There is one more issue. The native accordion has accessibility issues that do not seem easy to describe for assistive technologies; therefore, it may be better to stick with custom-built Div tags and roles.
