An alternative solution is to embed the info in PROMPT. In order to
avoid wasting 20 lines of the TTY real estate on each command, you can
automatically contract the prompt before executing each command. Thus,
if you run `pwd` twice in a row, your TTY might look like this:

    me@box ~ % pwd
    me@box ~ % pwd

    me@box ~ % █

In this approach the extra info ("foo=bar", etc.) is always displayed
right above the current prompt. This is basically Transient Prompt
from Powerlevel10k
but with a fatter prompt.
