+// Dev-only: seed the asset-path global for the standalone dev host page.
+//
+// Production consumers (e.g. dashboard) call setAssetPath(...) themselves
+// before loading the bundle, pointing it at wherever they serve the
+// images + datasets. In dev the standalone index.html IS the consumer,
+// so we inline the assignment here.
+//
+// Import this FIRST in indexDev.tsx so the global is set before either
+// `setPublicPath` reads it for webpack's `__webpack_public_path__` OR
+// the direct readers in `index.tsx` / `SelectDataset.tsx` build URLs
+// from it. ESM guarantees depth-first evaluation in import order, so
+// this module's body runs before any later import is evaluated.
+//
+// Value: './' — webpack emits images to `images/` (in-memory, served by
+// webpack-dev-middleware) and `webpack-dev-server --static public`
+// serves `public/datasets/*` at `/datasets/*` on disk. Both sit at the
+// root, so the single-prefix model works.
