# ~/code clone (NOT a hardcoded /home/wizard/code) and names the Claude session
# after the tmux session so /resume, the prompt box, and the terminal title line
# up. Deployed via /etc/skel by setup-devvm.sh, so new accounts get it on
# `useradd -m`. Existing users are repointed to this during their migration.
