inconsistent use of 24-hour / am-pm clock

[jsoref]

1. Visit https://githubunwrapped.com/ghost
2. Play through until you get to the frame that animates calculating the most productive time:

Note that the bar graph is going from 0..23 but the spinner is showing am/pm.

Expected results: one or the other time representation, but not both. (Personally, I prefer am/pm.)

That could mean showing 12a and 12p instead of 0 and 12 for those bar points (the a and p could be wrapped to second lines).
