+// FINAL GUARD: Disable ALL Minification for SQLite-WASM stability
+// ============================================================
+// WHY THIS FILE EXISTS:
+//   Kotlin/JS loads webpack.config.d files in alphabetical order.
+//   This file is prefixed with "z_" to ensure it runs LAST —
+//   AFTER Kotlin/JS and all other plugins have had their chance
+//   to set config.optimization. This guarantees that no Terser
+//   or other minimizer plugin can re-enable itself after this point.
+//
+// ROOT CAUSE:
+//   sqlite3-worker1.mjs contains a top-level `return` statement
+//   that is valid for browser-worker scripts but crashes Terser.
+//   Disabling minification for the entire shell module is the
+//   most stable fix in the context of WASM-heavy KMP projects.
+//   (Performance trade-off is negligible for WASM bundles.)
+//
+// REFERENCE: docs/99_Journal for build history.
+// ============================================================
