Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

The Rules of Margin Collapse
FWIW, while there are unfortunately only very few attempts at formalizing CSS, there's at least an unofficial, unreviewed (?), partial formal semantics for (CSS 2-era) float layout based on z3 SMT and Racket you can take a look at to get a flavor, though it isn't receiving further development.

W3C’s transfer from MIT to non-profit going poorly
Do we need W3C anymore? The HTML 5 specification has been created by WHATWG for many years now, with W3C only rubber-stamping historic WHATWG versions until 2017 or so. SVG2 is going nowhere, and so isn't MathML, leaving the CSS working group as W3C's remaining point of influence over the Web. CSS is regarded as so poor and overdone a specification that the only two external projects for a formal specification have failed or remained woefully incomplete (1, 2).

Is There Too Much CSS Now?
1. CSS should've been split into app-y styles and doc-y styles a looong time ago; meaning that when you need JavaScript to make use of a feature anyway, there's no point in using CSS and it's better to set styles, layout using JavaScript rather than bloat CSS. The Houdini API was on the right track years ago.
2. The CSS WG at W3C must deliver formal specification rather than the prose they're writing up now. For an idea how a (partial) formal spec for CSS rendering looks like, see eg. [1], [2] (with limitations).
The one way complexity that both W3C and WHATWG have delivered over the past 15 years with complete lack of mental discipline due to financial dependency/job security will be a major source of confusion for generations to cone, and will not be looked at favorably.

Verifying GCC optimizations using an SMT solver
There's this cool project using z3 (and racket) for formalizing CSS rendering [1] I never came around to lift for anything. Maybe someone else interested in leading the web out of the dark ages and give W3C's CSS WG an idea what we expect from them will.

Ladybird: A new cross-platform browser project
FWIW, I know two (partial, kinda) formal specifications of CSS normal flow and float layout, both of which are finished ie dead projects:
[1]: https://lmeyerov.github.io/projects/pbrowser/pubfiles/paper....
[2]: https://github.com/uwplse/cassius
(not counting the 1990s constraint CSS effort).
The first was merely part of a parallel compiler project and also covers table layout, whereas the second is a Racket (Scheme) program to formulate the HTML doc and CSS rules as a theory for submitting to z3 SMT to solve all kinds of decision problems (it can also produce a rendering).
Not sure that's very helpful; it would be cool if W3C can invest some time into better specs (not just prose).

JavaScript is not single-threaded
You forgot to mention (Web)Workers. This is explicit creation, management, and communication with additional threads within JavaScript. What's more, they've been around in JavaScript longer than the V8 engine has even existed!

Speedometer 3.0: A Shared Browser Benchmark for Web Application Responsiveness
> Is it though?
In my experience it's the buggiest browser out of the big three, and is often missing basic features like e.g.:
https://caniuse.com/?search=opus
Supported in Firefox for *12 years* now, in Chrome for 10, still no support in Safari.
They only "support" Opus audio in their special snowflake '.caf' container, which is super buggy and the last time I checked no open source program could even generate Opus '.caf' files that could be played by Safari on all Apple platforms. I ended up writing a custom converter which takes a standard '.opus' file and remuxes it on-the-fly (I only store '.opus' files on my server) into Safari-compatible '.caf' files, taking special care to massage it so that it avoids all of their demuxer/decoder bugs. You shouldn't have to do this to have cross-browser high quality audio!

Streaming HTML out of order without JavaScript
Well I'll be! In my mind I had this clear picture of Firefox implementing it.
It correct, it was only Chrome: https://caniuse.com/?search=html%20import

IPissed: Apple is after web capabilities to protect close to 100B App Store Tax
https://caniuse.com/?search=web%20bluetooth
which might be great because you have the choice...
and you can use open source chromium or brave (like the jvm to run cross platform java) to run web apps seemlessly that need web bluetooth or such but use safari or firefox for personal use if you find them more secure
I mean using chromium engine as the running environment where chromium only ever runs special trusted web domains and never goes to other "malicious" web domains that may fuck up iOS as Apple claims would be still a secure choice
like you will not download spyware from Apple Store because you are an adult not because Apple can protect you there
