+The apps use `st.spinner()` to show a spinning icon when the model is running,
+but this does not work with `stlite`. Hence, it may appear like nothing is
+happening, when the model is actually running behind the scenes (once you
+click "simulate"). This is mainly relevant to the stroke model which takes a
+little longer to run, but you can speed it up by reducing the number of
+replications.
