TerrainTools — Terraforming Toolkit (3-in-1)

EN | Merges former BedrockReplacer + Seitiassist + CaveEraser. Toggle each module in config.yml.

• bedrock: replace bedrock with deepslate per chunk/radius (bottom layer protected) — great for nether ceilings
• seiti: clearing wand (diamond cost), 1x1–7x7 area pickaxe, 9x9–21x21 mega pickaxe, offhand fluid solidifier (lava→obsidian, water→cobblestone), smart trash GUI via sign
• cave: BFS underwater-cave detection & filling + chunkfill rough mode; optional emerald cost via CasinoPlugin

Commands are OP-only — players use distributed tools & signs. Configs fully compatible with the original plugins.

JA | 旧BedrockReplacer＋Seitiassist＋CaveEraserの統合版。岩盤置換／範囲整地アイテム5種／水中洞窟埋立。コマンドはOP専用、プレイヤーは配布アイテムと看板で操作。旧config完全互換。
