% ElegantBook loads biblatex internally. Polyglossia must be loaded first, so
% register it on LaTeX's package hook before delegating to the upstream class.
% fvextra loads lineno later; bidi requires lineno to have been loaded before
% bidi/polyglossia, so keep this ordering dependency in the early hook.
