#!/usr/bin/env node
// Build the GPL standalone for the BACKED editor deployment (editor.pcbjam.com):
// remote mode against the closed API (projects, libs, auth session cookie) with
// Yjs board rooms on the same API host (path-routed to the sync worker), pinned
// to the same CDN WASM root + per-tag manifest as the demo. The mirror of the
// closed repo's scripts/dev-all.mjs standalone env, with prod origins.
//
//   node scripts/deploy/build-editor.mjs --tag v1.2.3 --api-base https://api.pcbjam.com
//
// Unlike build-demo.mjs there is NO static gallery, NO IDB project layer and NO
// CDN libs pin: projects and libraries come from the backend (VITE_LIBS_SOURCE=
// synced → the server's r2-idb-sync bridge). WASM still comes from the CDN.
