COI: Extended unifies former gameplay overhaul modlets (Logistics, World, Solar, Structures + expanding Agriculture/Fishing) into a single Unified Core while preserving a small set of standalone, opt‑in quality‑of‑life / cheat / utility mods.
Choose ONE primary path per save: Unified Core (new games), Updated Legacy bundle (finish old overhaul saves), or StandaloneONLY (QoL/cheats only).
QUICK PICK:
• Starting a NEW game? Use the Unified Core.
• Finishing an existing overhaul save? Use the Updated Legacy bundle.
• Only ever used QoL / cheats? Use StandaloneONLY.

Originally split into multiple gameplay modlets because of strict product ID limits, COI: Extended now leverages the expanded 65,000 product space to merge major overhaul content into a single Unified Core.
Goals: faster iteration, deeper balancing, less mod clutter, and a stable foundation for new systems (Agriculture, advanced logistics, world progression, etc.).
Standalone utility / cheat / QoL modlets remain separate so you can customize difficulty or add convenience without committing to the full overhaul.
