# token itself by exchanging the `refreshToken` in the mounted credential file,
# so `/data/claude` may stay read-only. Use the `with-claude-cli` stage below
# when you need to *create* a credential inside the container.

# TLS roots only. `POST /api/login` (issue #47) drives the Claude Code CLI on a
# PTY, so that surface needs the `with-claude-cli` stage below; this base image
# stays minimal for the mounted-credential deployment.
