There are 2 places where prices per trace are listed, and they seem inconsistent (or if not inconsistent, I'm getting confused). Which of these is true?

Here, it suggests additional traces are $0.005/trace:

Here, it suggests additional 14-day traces are $0.50/trace = $0.0005/trace (10x cheaper), and 400-day traces are $4.50/trace = $0.0045/trace (10% cheaper):

Also, can you confirm that a trace includes all spans under it (i.e. if an API request logs 1 trace with 20 spans under it, we're only charged for 1 trace)? I think this is already implied, but the abundance of clarity would help

Thanks!
