On starting the shell, (within zsh at the moment, because fish isn’t

from within the zsh initialization files. Is it reading my zsh
initialization files to
get that information, or or getting that information from some other
source?
Environment variables are passed from parent processes to their
children. That's why they are called "environment" variables. A shell
also has variables that exist for its own use in command lines that are
NOT part of the environment. You can see all shell variables using the
'set' command and all environment variables with the 'env' command. You
can turn a normal variable into an environment variables with 'export
VARIABLENAME' and POSIX-compliant shells can also be configured to
export all variables automatically.
TL;DR: you'll need shell init files for fish.
