Neither Home Depot nor eBay understand how people use passkeys. I have passkeys set up with both: eBay never presents me with the option, Home Depot doesn't trigger 1Password, only the browser-stored option (I'm guessing... no other site acts that way)

Is there a good, plain 'ol CSS formatter out there, especially one that's NOT based on JS? I don't love pulling those tools into my projects, would prefer a statically compiled tool.

My daughter came home from her first day of 4th grade yesterday having learned about the Hailstone Sequence. It took me a bit to remember it's "real" name, the Collatz Conjecture. I wish I were in 4th grade again.
