% ORCID logo. Shape data derived from the CC0 simple-icons project
% (https://simple-icons.org), flattened to absolute M/L/C/Z commands with the
% y-axis pre-flipped for TikZ and scaled to ~2.5cm (svg.path ignores TikZ
% coordinate transforms, so the transform is baked into the coordinates).
% The ORCID logo is a trademark of its owner; used here for identification.
