# Optional multi-account routing: "ddev claude --account <sel>" starts a session
# pinned to a claude-swap account via "cswap run". With no flag, a project
# default can come from $DDEV_CLAUDE_SWAP_ACCOUNT or the first line of
# .ddev/claude-code/claude-swap-account. When neither is set this behaves
# exactly like a plain Claude Code launch.
