I didn't cover everything in my response due to character limitations.
Although I can't provide a full explanation, it's worth noting that the clamp function resolves to max(MIN, min(VAL, MAX))
. You can find more information at https://developer.mozilla.org/en-US/docs/Web/CSS/clamp(). When the first parameter is 0 and the second has a unit, max and min behave similarly.
There are numerous posts on Stack Overflow with many accepted and upvoted answers that now seem inaccurate because they claim that 0 and 0px are equivalent (according to the specification as far as I can tell).
It could be a bug or a feature, but it's crucial to be aware of this distinction. Thank you for bringing attention to it.
