- Replace getTemporaryDirectory() + OpenFilex.open() with getDownloadsDirectory() (fallback to temp) so the .eml file lands in the public Downloads folder instead of triggering Android's "open with" dialog. - Show a SnackBar with the saved path after download instead of launching a file viewer. - Display the email size (via fmtSize) at the top of the Raw Email dialog, above the scrollable content. - Add widget test covering the size display in the Raw Email dialog.
