/**
 * Pre-build Remotion Bundle for Packaging
 *
 * This script runs BEFORE electron-forge packages the app.
 * It pre-bundles the Remotion project so the packaged app
 * doesn't need to call bundle() at runtime (which requires
 * webpack and other heavy deps).
 *
 * Usage: node scripts/bundle-remotion.js
 * Output: out/remotion-bundle/
