+// Launch the desktop renderer with HMR disabled so the React Fast Refresh
+// preamble path is skipped. This sidesteps a current Vite 8 / plugin-react 6
+// bug where the preamble script is not injected into index.html → renderer
+// throws "$RefreshReg$ is not defined" on every TSX module → React tree
+// never mounts.
+//
+// We're not trying to use HMR while profiling typing lag anyway. Hermes desktop
+// boots, you type, profiler measures. HMR off is fine.

+// Usage: node apps/desktop/scripts/dev-no-hmr.mjs
