% Fix label width so every line of every reference is indented consistently,
% regardless of whether the displayed number has one, two, or three digits.
% With reversed numbering, internal label N maps to displayed "1" and internal
% label 1 maps to the highest displayed number (= entrycount). biblatex sizes
% \labelnumberwidth from the largest *internal* number, which after reversal is
% the *smallest* displayed number, making the box too narrow for double-digit
% (or larger) displayed labels. Redefining the bibliography environment here
% forces the box width to match the actual maximum displayed number.
