TIL that this quick trick [1] also would have prevented this:

  ${STEAMROOT:?}

...where :? throws an error if the variable is unset or empty. (Still far too scary for my taste, though!)

Or you just do

  set -euo pipefail

as the first thing in your bash script which you absolutely should do every single time.

Note that's bash not POSIX though right?
