+ *   - Clicking on the dimmed overlay does NOT close the dialog (default: false).
+ *   - Pressing Escape does NOT close the dialog (default: false).
+ *   - Both behaviors can be opted-in via ``closeOnOverlayClick`` /
+ *     ``closeOnEscape`` for the rare cases where this is desired.
+ *
+ * Layout: standard 3-row flex (header / scrollable content / optional footer).
