Which axis carries a trace's error bars, or null when it draws none.
Plotly resolves an error_x/error_y container onto every trace that
could carry one, so the visible flag — not the container's presence — is
what says a chart drew intervals. A trace with both gets its vertical ones
read: a MAIDR error-bar layer carries one interval per sample, and the
vertical is the one a reader means by "the error bar".
Lives here, beside the selector, because the two must agree: reading the
y bounds while highlighting path.xerror would announce one interval and
light up another.
