+/**
+ * E2E regression: in-page route navigation must preserve the chosen UI scale.
+ *
+ * Desktop is a HashRouter over one file:// document, so every route is a
+ * distinct URL to Chromium's per-URL zoom store, and a route with no record of
+ * its own resolves to the host default (100%). In-page navigation fires no load
+ * or window event, so nothing re-asserted the persisted level: switching
+ * sessions dropped the window to 100% while Appearance kept reading the chosen
+ * scale (#48658, #38854, #79863).
+ *
+ * Prerequisite: `npm run build` must have been run so dist/ exists.
