Control nodes. Trails auto-build between what you own. Food flows;
Material stays. Vision is your owned network + hop-2 along the trail
graph; unknown terrain is a soft veil, not a blackout. Cosmetics-only
monetization.
Train grows unitPool. The slider is rush ↔ eco (army vs larvae), not a
separate mode. Extend into a rival to start a fight. Shift-click abandon
still kills trails.
