%% The implementation of footnotenosplit.sty for LaTeX with the
%% socket-based \@makecol (LaTeX2e 2025-06-01 or later; pdfLaTeX,
%% LuaLaTeX, XeLaTeX, ...), loaded by the main package; do not load

%% This file uses the build/column/before hook, executed at the very
%% beginning of \@makecol, to discard an "empty" \box\footins
%% (\ht\footins < \footnotesep, i.e. no actual footnote line).  The
%% subsequent \@outputbox@appendfootnotes then sees a void \footins and
%% emits neither \footnoterule nor \skip\footins.
