"""Capture beat driver — drive the live app through the demo beats deterministically.

This does NOT record video itself. Use it alongside Cap desktop, or point
scripts.record.py at an existing Chrome CDP endpoint. The script walks the UI
slowly with deliberate pauses while YOU (or cap-cli) capture the screen.

The UI tabs are LOAD · SLICE · PRINT · REVIEW. Selectors prefer stable IDs
over visible text wherever possible, so renames are less likely to break this
script than the previous text-only version.

One-time setup (local; not a Space/runtime dep):
    uv pip install playwright && uv run playwright install chromium

Run the app first in another terminal:
    make run                      # http://localhost:7860   (pre-warm one analyze!)

Then walk the beats (headed browser; record it with Cap):
    uv run python -m scripts.capture --beat all
    uv run python -m scripts.capture --beat 3            # load-bearing beat
    uv run python -m scripts.capture --beat benchy       # LOAD + Benchy quick-load
    uv run python -m scripts.capture --beat loop         # the learning loop

Options:
    --url      Space or local URL (default: https://node.microfactory.space)
    --slowmo   ms between Playwright actions (default 350)
    --pause    seconds between beats (default 1.5)
    --headless hide the browser (no recording)
