Flesh out Pre-Elysium worldbuilding: expanded and rewrote many movement and faction entries (adding social, political, and cultural texture and a new Free Neural Network entry), created several defunct company profiles, and added numerous historical/timeline event files under Pre-Elysium/Timeline/Events. Also refined core guidance and framing: updated AGENTS.md wording, the Aetheria Introduction, Politics (PSC order and on-the-ground effects), Colonizing Sol, and Post-Elysium tech notes (Aetheric Drive). These updates deepen lived experience, clarify institutional dynamics, and provide connective context for later Post-Elysium continuity.
