This is a petty comment, but I have to make it: for a company as rich as Figma, and who's identity is design software, it's very jarring to see such horrendous math rendering (or lack thereof) in their blog.
This might be just a personal rant, but I hate, despise, abhor squircles.
For some (irrational, I admit) reason, to me they are a visual reminder of all that went wrong in computing since the times the rounded rectangle was king. The vision of squircles in any UI instantly produces in me a sensation of a patronizing voice saying "don't you just LOVE walled gardens and app stores and closed hardware and ads and...".
Of course the squircles themselves are innocent, but what can I do.
