This top section looks great, but I wonder if there's something we can do to make the bottom two images appear clickable. Currently, there's not really any visual cue that tells me they are links, other than when I hover them, but that's not available on mobile.

Not sure how... overlay a link arrow over the images? Or an arrow next to the card titles?

To be consistent, I think we want to end the section subtitles with a ., e.g. here:

The community's official channel for answering questions and discussing the development of Swift. ←

For the "Contribute to Swift" section, maybe we can change the subtitle a bit, e.g. to:

Swift welcomes contributions from everyone, whether you write code or help in other ways.

Many of the card descriptions are truncated. We should try to tweak them to be a bit shorter maybe to not truncate for more viewport widths.

I also noticed that some are still WIP descriptions, e.g.: Topics related to the Swift Evolution Process. Another line here.

Mentioning this here as it wasn't called out in the PR description to be missing.

It should be possible to compress the images. I tried one of them and managed to reduce the file size by 75% using a lossless compression.
