🗺️ Expansions 擴地

What it does 做乜嘢

Around forty land parcels, each costing escalating coins and two to six permits earned from ship chests, the mine and achievements. 大約四十塊地，每塊要遞增嘅金幣，同二到六張用船寶箱、礦場同成就賺返嚟嘅許可證。

How it works 點運作

Permits are deliberately not purchasable with coins, so expansion is paced by play across three different systems (ship, mine, achievements) rather than by grinding any single one. 許可證刻意唔可以用金幣買，所以擴地嘅節奏要靠三個唔同系統（船、礦場、成就）一齊玩先夠，而唔係死磨一個系統。

Failure modes 失敗情況

A parcel that cannot yet be afforded simply stays locked with its exact remaining cost shown — there is no scenario where an expansion becomes permanently unreachable, since coins and permits are both renewable resources. 暫時買唔起嘅地皮就會鎖住，清楚顯示仲差幾多——唔會有擴地變成永遠解唔到嘅情況，因為金幣同許可證都係可以再賺嘅資源。

What is not yet implemented 仲未整好嘅部分

The published v0.1.0-22 desktop baseline is available (see the changelog). The full parcel list, its coin/permit costs, and its unlock order are balance data validated for reachability alongside everything else. 已發佈嘅 v0.1.0-22 桌面基準而家可以下載（睇更新日誌）。完整地皮清單、金幣／許可證成本，同解鎖次序，都係平衡數據，同其他嘢一齊做可達性驗證。
