% Even sides end up on the left, hence we want 6mm margin here.
% The right (even) side margin is computed from the edge of the left subpage, but since we have set
% hoffset to -1in, we need to undo this overlap by setting oddsidemargin to 1in.
% We don't add 6mm to oddsidemargin, since the position is computed relative to the left subpage,
% which is already offset by 6mm.
