Historic Preservation Zone

Historic Preservation Zone adds one tool that freezes the current look of a town. ENTRY - A new button appears in the top-left mod button area, in the same row as the game's own layer buttons. Click it to open the tool window; click it again, press ESC or the title bar X to close it. DRAW - Click "Draw area" and then click the map point by point to outline any shape. Left click adds a corner, moving the mouse shows a preview polygon plus a rubber band from the last corner, right click removes the last corner, and clicking the first corner again (within about 8 m) closes the area and applies it right away. Every corner is marked with a dot and the area is filled with a translucent green preview, so the very first click already gives feedback. PROTECT - When the area closes, every existing town building inside it is flagged as historic. The town can no longer upgrade, rebuild or demolish those buildings, so their current look is preserved. Empty lots inside the area still develop normally. Nothing is blocked for the player: building and bulldozing work as usual. MANAGE - Protected zones are shown as translucent green areas while the tool window is open. Click a zone to select it (amber outline); the panel then shows its number, building count and creation year, together with "Delete selection" and "Clear selection". Deleting a zone unlocks its buildings again, while buildings still covered by another zone stay locked. SAVES - Zones are stored in the savegame and restored when it is loaded. Up to 256 zones per savegame. The interface follows the game language (English / Simplified Chinese). No models or base game resources are replaced, so conflicts with other mods are unlikely. Buildings that are already flagged stay historic even after the mod is removed, so delete your zones before uninstalling.

「历史风貌保护区」只做一件事：把城镇此刻的样子冻结下来。 入口 - 屏幕左上角模组按钮区会多出一枚「历史」图标（与本体图层按钮同一排）。点击打开工具窗口；再次点击、按 ESC 或点标题栏 X 即可关闭。 圈选 - 点面板上的「绘制区域」，然后在世界里逐点点击围出任意形状：左键添加顶点，移动鼠标时显示多边形预览与从最后一个顶点拉出的橡皮筋，右键移除上一个顶点，再点回第一个顶点（约 8 米内）即闭合并立即生效。每个顶点都有圆点标记，区域以半透明绿色预览，所以点下第一个点就有反馈。 保护 - 区域闭合后，范围内所有**现有**的城镇建筑会被标记为历史建筑。城镇开发商不再升级、重建或拆除它们，现有外观得以保留；区域内的空地仍会正常生成新建筑。对玩家没有任何限制：建造和拆除照常可用。 管理 - 工具窗口打开期间，已保护区域在地面上显示为半透明绿色色块。点击任意区域即可选中（琥珀色描边），面板会显示编号、建筑数量与建立年份，并提供「删除选中区域」「取消选择」。删除一个保护区会让其内部建筑重新自然发展；同时仍被其他保护区覆盖的建筑保持锁定。 存档 - 保护区写入存档，读档后自动恢复。每个存档最多 256 个保护区。 界面语言跟随游戏语言（简体中文 / 英文）。不替换任何模型或本体资源，与其他 mod 冲突面很小。已被标记的建筑即使卸载本 mod 也保持锁定，卸载前请先删除自己的保护区。
