# Run as fred so it has access to ~/nixos-config and the rest of the home dir.
# Auth is handled entirely by Authelia (auth = "none" disables code-server's own
# password gate). After deploy, install the Claude extension from a terminal:
#   code-server --install-extension anthropic.claude-code
# and set ANTHROPIC_API_KEY in ~/.config/code-server/env or via a shell profile.
