+# downloads its binary on the first require('electron'). Its install.js
+# uses @electron/get (ESM, loaded via require(esm)) and extract-zip. On
+# recent Node (observed on Node 26) the extract-zip stage silently exits
+# 0 without writing node_modules/electron/path.txt, so subsequent
+# require('electron') calls fail with ENOENT.
+#
+# This script downloads the binary with @electron/get (which works on its
+# own) and extracts it with the system `unzip`, then writes path.txt the
+# way install.js would have.
