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.

How do a compress a json to fit on neocities
Otherwise, compress the images more. https://entropymine.com/imageworsener/ is a versatile multitool with a learning curve. Many image editors have support for downscaling images and compressing JPEGs. pngquant is a PNG-specific tool, if you like PNGs a lot.

Text Rendering Hates You
There can be various causes for those symptoms:
1. Even if the rendering gets the subpixel order right, the subpixels are rarely equidistant on a display. They tend to be closer to each other within a logical pixel.
2. Some subpixel-AA algorithms are naive, and trade color accuracy to luminance accuracy, causing more color fringes.
3. Incorrect gamma handling.
4. If aiming for more luminance accuracy, incorrectly taking into account the relative luminance of the subpixels (what you observed with the brighter green subpixels).
Imageworsener[1] has an option to downscale with subpixel antialiasing, it's gamma correct by default, and it has an option for adjusting the subpixel offsets within a pixel (instead of the naive default of 1/3). It might be a good way to try out correct subpixel-AA, but it only works on images. I guess you can render text on high resolution and downscale that with imageworsener, but you won't get any hinting that way, but maybe that's desired.
Very few software does AA correctly, let alone subpixel-AA.

Libsodium: A modern, portable, easy to use crypto library
For C/C++ projects that use meson as the build system, there is an excellent way to manage dependencies:
https://mesonbuild.com/Wrapdb-projects.html
https://mesonbuild.com/Wrap-dependency-system-manual.html
meson will download and build the libraries automatically and give you a variable which you pass as a regular dependency into the built target:
https://github.com/qemu/qemu/tree/005ad32358f12fe9313a4a0191...
https://github.com/harfbuzz/harfbuzz/tree/main/subprojects
https://github.com/harfbuzz/harfbuzz/blob/37457412b3212463c5...
Or, if you're using proper operating systems, they're managed by the usual package manager, just like everything else.

Text Rendering Hates You
If you sympathize with the travails of people working on text rendering in applications, please consider supporting (among other projects):
1. The LibreOffice project (libreoffice.org), the free office application suite. This is where the rubber hits the road and developers deal with the extreme complexities of everything regarding text - shaping, styling, multi-object interaction, multi-language, you name it. And - they/we absolutely need donations to manage a project with > 200 million users: https://www.libreoffice.org/donate
2. harfbuzz (https://harfbuzz.github.io), and specifically Behdad Esfahood the main contributor. Although, TBH, I've not quite figured out whether you can donate to that or to him. At least star the project on GitHub I guess.

ImGui or text rendering libraries
As for text, it depends very heavily on what exactly you need. Simple ASCII text and bitmap fonts? Just do it yourself or get a .bdf parser. Simple Latin/Cyrillic-like writing with ok-looking vector fonts (ttfs)? stb_truetype has all you need. Font hinting, subpixel rendering? You use freetype. More complex writing like Arabic? You will have to do shaping as well, say with HarfBuzz. Need right-to-left or unidirectional text? Hypenation? Go for platform APIs if you can (DirectWrite om Windows, CoreText on Mac).

QuestPDF: Modern .NET library for PDF document generation
Gold standard? Even though serious bugs are not fixed [1] because "the code is too fragile to touch at this point"? Looks like Android uses HarfBuzz, if so it can't be that bad.

A Programmable Markup Language for Typesetting [pdf]
The linked libraries are not even close to solving limited subsets of problems solved by FreeType or HarfBuzz. No test is needed if they do not even have a working implementation of particular requisites: Do they work on heterogeneous layouts, directions, languages, locales, scripts, symbols and composites, extensions, variations, legacy, missing, partial or corrupted instructions, standards interpretations, platforms, output devices, nonstandard point structures and grids?
They do not. What they solve is almost a toy problem compared to the size, scope and breadth of these libraries.
Just because some project is implemented in Rust does not make it comparable never mind superior by default.
There is a world out there and it is not homogeneous format and standards-compliant Latin fonts in English LTR text in linear disposition with some generic rectangular subpixel rendering on a regular rectangular grid.
I warmly welcome you to browse closed issues of FreeType [1] and also the closed issues of HarfBuzz [2]. If you feel inspired please do also look into mailing lists and discussion pages related to the development, building, tracking and patching of packages of these projects in any of the numerous places it is used.
The only argument Rust people have is in relation WASM but if you insist in targeting WASM why not fork FreeType, strip it to the strict subset of features your application needs and target it?
Why do it in the first place? Why reinvent the wheel?
As such I will restate my view: I see no gain in using any of these subpar libraries.
