# Headless agentic UI iteration stack.
#
#   tauri-headless : the dev (debug) app + Xvfb + tauri-driver (port 4444),
#                    driven by Claude Code through the tauri-docker MCP
#                    (docker exec -i tauri-headless npx -y github:VoltiusApp/mcp-tauri-automation).
#   ssh-host-1     : a throwaway SSH server (linuxserver/openssh-server) so the
#                    app has a real host to add / connect / SFTP against.
#
# Both services share one user-defined network, so the app resolves the host
# by name (ssh-host-1). It listens on port 2222 with password auth —
# user "voltius", password "voltius".
#
#   docker compose -f compose.headless.yml up -d
#   docker compose -f compose.headless.yml logs -f tauri-headless   # wait for tauri-driver
#   claude mcp add tauri-docker -- docker exec -i tauri-headless npx -y github:VoltiusApp/mcp-tauri-automation
#
# NOTE: tauri-headless needs seccomp=unconfined — the app's OS keychain uses the
# kernel keyutils keyring, which the default Docker seccomp profile blocks
# (otherwise the app hangs on its splash).
