# Per-repo Claude Code login: a `.claude-config-dir` marker at (or above) the
# cwd names a config dir; while inside that tree CLAUDE_CONFIG_DIR points at
# $HOME/.claude-<name> (or an absolute path if the marker holds one), so
# `claude` and `dev-launch claude` both pick up that login. Leaving the tree
# restores whatever was set before. Sourced from ~/.zshrc.
