# Unit systemd de UTILIZATOR pentru puntea Discord -> Claude Code (LXC 171).
#
# Se instaleaza in ~/.config/systemd/user/claude-discord.service (vezi install.sh).
# Rulare ca utilizatorul `claude`, NU ca root: puntea are exact accesul pe care il
# are omul la terminal — decizie de arhitectura, nu scapare (vezi README, Securitate).
