Thanks a lot for doing this 🙏 , I have some comments though:

It would be great to replace all the favicons without the "Tetragon" text. Just the logo.

The aliasing sometimes looks completely off on the main logo in the top left corner, I'm not sure we use a SVG here but that could explain, maybe it's better to have a bitmap file like a png for this use case. It's not really problematic we can still fix this later.

Then nits: this one is not centered, and we would need to redo the main image or make it less big but that's maybe out of scope:

Got it! I'll replace the favicons with the logo containing just the shield. For the logo on top, I'll switch it to a png and see if it changes.

The hero logo needs to be reworked to fit the landing page and also the one on the getting started docs page too. I tried to adjust it with css but it just wouldn't centralize.

Thanks that's nice!

yeah don't spend time and worry about that we'll do that later :)
