+#!/bin/sh
+# Install a Node.js 24 (LTS) runtime under ~/.local/share/copilot-node/ for the
+# exclusive use of copilot.lua / copilot-lsp inside neovim. System-wide nodejs
+# (currently 26.x in Arch) is unaffected.
+#
+# Background: copilot-language-server is incompatible with Node 26's default
+# fetch implementation. Multiple upstream issues, no fix yet:
+#   https://github.com/zbirenbaum/copilot.lua/issues/695
+#   https://github.com/github/copilot.vim/issues/282
+#   https://github.com/github/copilot-language-server-release/issues/45
+# Symptom: "HTTP 200 response does not appear to originate from GitHub".
+# Workaround universally confirmed in those threads: use Node 24.
+#
+# chezmoi re-runs this only when the script content (and thus NODE_VERSION)
+# changes. Bump NODE_VERSION + NODE_SHA256 below to upgrade.
