+/**
+ * Vite configuration for the application.
+ *
+ * @remarks
+ * This configuration is mostly standard Vite + React setup, with specific accommodations for:
+ * - WASM decoders used by Cornerstone libraries
+ * - DICOM parser which currently uses CommonJS format (planned migration to ESM)
+ *
+ * @description
+ * Key configuration points:
+ * - Uses vite-plugin-commonjs to handle the DICOM parser's CommonJS format
+ * - Configures worker format as ES modules
+ * - Excludes Cornerstone CODEC packages from dependency optimization to handle WASM properly
+ * - Explicitly includes dicom-parser in optimization
+ * - Ensures WASM files are properly handled as assets
+ *
+ * @example
+ * To use additional WASM decoders, add them to the optimizeDeps.exclude array:
+ * ```ts
+ * optimizeDeps: {
+ *   exclude: [
+ *     "@cornerstonejs/codec-new-decoder",
+ *     // ... existing codecs
+ *   ]
+ * }
+ * ```
+ */
