"""Thin CLI over demoprep_app.portal.login_clone — for local testing only.

The real path is the background job build_demo_from_brief starts for
demo_type="tse" (mcp_server.py), which calls the same clone_login(). This wrapper
runs capture + generation for one site and leaves everything on disk for review:

    python scripts/clone_login.py https://www.example.com --company "Example" \
        --use-case "Retail Sales" --out /tmp/clones/example

    <out>/capture/screen-*.png        the real site, as the model saw it
    <out>/clone/shots/*-render-*.png  the clone, rendered
    <out>/clone/app/                  a pristine template with the clone in place
                                      (cd there and `npx vite` to click through it)
    <out>/clone/result.json           rounds, tokens, timings, why it failed if it did

Needs ANTHROPIC_API_KEY (read from .env) and Playwright's Chromium
(`playwright install chromium`).
