# ── Host-shared shell customizations (devbox-shell bridge) ───────────
# If the host bind-mounts a directory at ~/.config/devbox-shell/ (the
# recommended pattern for sharing aliases/PATH/utilities between host
# and container), source the bash_aliases file from it. This survives
# --force-recreate because it's baked into the image's skel, not the
# container's writable layer. Hosts that don't use this pattern are
# unaffected — the test silently skips if the file doesn't exist.

# The guard MUST stay shell-local (NOT exported): if it leaks into child
# processes, every nested shell -- crucially each tmux pane, which inherits
# the tmux server's env -- skips installing `history -a` and only persists
# history on a clean exit. Abrupt termination (docker stop, tmux kill-server,
# SIGKILL) then loses that shell's in-memory history. Keeping it unexported
# means each new interactive shell re-installs its own per-prompt flush.
