app.css: Disable text/image selection globally; re-enable for input/textarea/[contenteditable] so typing and pasting still work. sender-page.css: Add .sender-preview-popup, .sender-preview-viewer-wrap and .sender-preview-pdf-viewer rules. DxPdfViewer requires an explicit pixel-height parent — percentage heights resolve to 0 inside popup body flex containers and cause DevExpress NullReferenceExceptions.
