+- Added `/basesettings pocket type <void|nether|overworld> <subtype>` with type-aware autocomplete and validation.
+- Defaulted new and unconfigured Pocket Bases to `void/the_void` and persisted each owner's selected biome.
+- Applied biome metadata across unlocked columns and new expansion rings without changing blocks, entities, inventories, portals, progression, or mob-spawning preferences.
+- Added an atomic, configurable biome-change payment that defaults to 16 netherite blocks and restores the prior biome and payment on failure.
+- Verified the feature with `./gradlew clean check jar`.

+# US-019: Change a Pocket Base biome
+
+As a **Pocket Base owner**, I want to change my Pocket Base biome so that I can control its biome-specific atmosphere and natural mob selection without rebuilding it.
+
+## Acceptance criteria
+
+- [x] A Pocket Base owner can use `/basesettings pocket type <void|nether|overworld> <subtype>` to select a compatible biome.
+- [x] Void supports `the_void`; Nether supports its vanilla biome subtypes; and Overworld supports its vanilla biome subtypes.
+- [x] New and previously unconfigured Pocket Bases default to the void type and `the_void` subtype.
+- [x] Each change atomically charges a configurable currency and amount that default to 16 netherite blocks.
+- [x] Selecting the active subtype or providing an invalid type/subtype combination is rejected without charging.
+- [x] Changing subtypes within the same type incurs the configured cost.
+- [x] The selected biome is applied across every unlocked Pocket Base column without changing blocks, entities, inventories, portals, level, or the mob-spawning preference.
+- [x] Newly unlocked terrain receives the selected biome.
+- [x] When natural mob spawning is enabled, Minecraft can use the selected biome for applicable natural mob selection.
+- [x] The selected type and subtype persist through restarts and appear in `/basesettings status`.
+- [x] The command, types, and compatible subtypes are offered through contextual autocomplete.
+- [x] Failed biome application or persistence restores the prior biome and does not consume payment.
