#!/usr/bin/env node
// ── @originmain/live build script ────────────────────────────────────────────
// Produces a single self-contained browser ESM bundle under dist/:
//
//   dist/index.js  — side-effect-only browser module, no external deps
//
// Run: node build.mjs  (or via "pnpm build")
//
// Design notes:
//  • Platform 'browser' — esbuild replaces process.env.NODE_ENV and
//    avoids injecting Node built-in shims.
//  • format 'esm' — the published package is "type": "module"; webpack/
//    turbopack will tree-shake and include it in the user's bundle.
//  • bundle: true — @originmain/live has no runtime npm dependencies so
//    bundling produces one fully self-contained file with no require() calls.
//  • minify: true — the hook ships inside the user's production bundle;
//    every byte matters.
//  • No type declarations needed — the package is a side-effect-only import
//    (`import '@originmain/live'`) with no exported symbols.
