#!/usr/bin/env bash
# One-liner studio recording for WSL + Windows Chrome + Cap Desktop.
#
# This script:
#   1. Sources the cap-cli-skill so `cap` is available.
#   2. Discovers the Windows host IP from WSL's default gateway.
#   3. Launches Chrome in app mode pointed at https://node.microfactory.space
#      with remote debugging enabled (if not already running).
#   4. Runs the Node-based studio driver, which uses npm/pnpm-based Playwright,
#      starts a Cap screen recording if none is active, warms the GPU via the
#      WARM UP button, then drives the full demo. It leaves the raw .cap
#      project — no export.
#
# Usage:
#   ./record-studio.sh
#   ./record-studio.sh --beat=3
#   ./record-studio.sh --beat=placement --pause=4
#
# Prerequisites:
#   Chrome installed at C:\Program Files\Google\Chrome\Application\chrome.exe
#   Cap CLI set up via ~/projects/cap-cli-skill/setup.sh
