Oasis Cottage Roof (Composite)

Route cards are the travel frontier: one card per travel shape, shortest trip on the left. Each card to the right completes more of the recipe or, when equally complete, costs less gil; the last card is the most complete plan found and, among equally complete plans, the cheapest. The full scope is always evaluated, so the frontier keeps the best plan found. Best value is the card the gil-plus-travel weighting prefers (adjustable in Planner settings). Adding a single world is checked exhaustively; larger routes search promising combinations, so they are best-found, not guaranteed global minima. Worlds already on your itinerary are free to revisit. Only market worlds are counted; vendor stops are separate.
