% The selectable languages and their order come from the project manifest
% ([targets.defaults].languages); the class hands them to langselect from the
% build file, so a single langselect-aware source needs no languages setup
% here. \olsTargetLanguage is likewise bridged from the per-build language
% before langselect loads. \title is deferred through osglecture's metadata
% queue and replayed after \LoadClass, so \lende is defined by the time it
% runs.
