% test-flowarrow-11bg.tex — exercises plan 11b.g:
%   flowarrow-style    = hollow | filled
%   valve-style        = valve | circle | edu
%   flowarrow-cloud-tip = true | false  (global + per-\mvar override)

% Runs the same model under several setting combinations to verify
% that the keys flip rendering as expected and that per-mvar
% override on a stock wins over the global default.
