+- Dashboard: UYSD haplogroup-map iframe now loads on Windows (Tauri origin forced to `https://tauri.localhost`).
+- Dashboard: clicking **+ New** now clears all form fields instead of retaining the previous run's inputs and parameters.
+- Dashboard: window title and home-page header corrected to "Yleaf 4.1" (display strings missed in the 4.1.0 bump).
