Frontier belts: bigger maps seed a contested mid-map deposit belt

Let the player pick their side of asymmetric matchups (Oort, Nimbus)

Add JSDoc typedefs + // @ts-check for the core sim shapes (no build step)

Faction asymmetry — pick a side with its own passive identity

Tier 1: seed the sim, attack-move/hotkeys, onboarding, rally-to-mine, tiebreak

Home ore on every doorstep + draw the Foundry and Arsenal

Asymmetric world modifiers: two starts that differ

Content: extend terrain to Nimbus, Helix, and Oort

Content: terrain — rough ground, high ground, and no-build zones

Tier 8: balance pass, anti-stall win condition, replayable caches

Tier 6: performance & scale for large maps

Configurable skirmish: AI speed, map size, and resource abundance

Add hidden resource caches discovered by exploration

Tier 4 AI parity + planet roster with per-world rule modifiers

Tier 4 foundation: placement validation, buildable expansion CC, guaranteed ore

Fix stacked resource nodes: same overlap bug, at map-gen time

First playable slice: 1v1 skirmish vs scripted AI on Ferros Prime
