/* Swarm Research: a landing page for the swarm research community.
   Shared by every direction so they differ in structure, not decoration.
   Concept: logos carry the page; text stays to a name and one line. Left-aligned throughout.
   Color: cool paper, ink, and the tracker's orange only for the escapee (the mark and Swarm Incidents). */
