# Tests for configuring ZINIT[...] settings via `zstyle ':zinit:config' ...'.
#
# NOTE: the test bootstrap pre-sets every ZINIT[KEY], which would mask the
# zstyle path. Each test therefore exercises the feature in a CLEAN
# `zsh -fc` subshell that sets a zstyle, sources the patched zinit.zsh
# (located at ${ZINIT[BIN_DIR]}/zinit.zsh inside the test env) and prints the
# resulting hash field.
#
# The subshell is captured with `$(...)` rather than zunit's `run`: `run`
# re-`eval`s its arguments in the *outer* process, where the bootstrap has
# already populated ZINIT[HOME_DIR] et al., which would clobber the inner
# `${ZINIT[...]}` reads we want to observe. Single-quoting the inner script
# defers those reads to the subshell; only ${ZINIT[BIN_DIR]} is expanded
# (concatenated in) by the outer shell to locate zinit.zsh.
