The operator's proposal: one module, holding a mesh seat node-environment, is
the only writer of the account's environment. It renders contributed variables
and PATH entries as a POSIX file shells source and as environment.d for the
graphical session. The shell's contribution shrinks to shell code; the shell
render-then-service-manager-again positions become options weighed against it.
Opened after the zsh module's rollout (to-be 38 WP5) was stopped: every machine
carries the same predecessor-written startup file, the module's block would
duplicate it and drop lines, nothing installs the prompt, and execute never
reads .zshrc. Weighs how modules contribute environment and shell code, where
the operator's own lines go, ordering, and what a contribution is addressed to.
