- Replace producer/demand class pricing with strict 1:1 origin assignment;
each settled system sells exactly its signature good at a discounted origin
price, and the catalog remainder becomes a hub pool resold by stations/capitals
- Make banded hop distance the dominant sell-price factor (x1.0 to x7.0),
with planet-type demand as a secondary +10% modifier, and cap every shop's
sell price at its own buy price to eliminate the v1 infinite-credit loop
- Add Stock.js for the time-gated daily batch (6 units per origin per wall-clock
day) — the economy's only stateful piece; wire it through GameScene,
SaveData capture/restore/reset, and the shop UI stepper clamp + SOLD OUT strip
- Update Economy.js with assignOrigins pass, new buyPrice/sellPrice/shopFor
logic, tradePreview stock-cap backstop (buyback exempt), and distanceFactor
- Rework shop UI: BuyList shows "N left"/"SOLD OUT" per batch-limited row and
clamps the stepper; ScoutPanel shows MADE IN (origin system) instead of GROWN ON;
ShopView wires stockRemaining/stockCapsFor/spendStock into preview and confirm
- Update all dev tests (economy, cargo, shop-ui, saves) to assert model v2
invariants including the anti-loop sweep, batch clamp/backstop, and save round-trip
