+ *
+ * Vite configuration for building the web application for Electron.
+ * This config outputs to 'dist/' (like the web build), sets VITE_PLATFORM to 'electron',
+ * and disables PWA plugins and web-only features. Use this when you want to package
+ * the web app for Electron but keep the output structure identical to the web build.
