 ### 第九阶段：剧情与收尾
 
+- 交易终端窗口加大：默认 1200×900，mod 设置里可选 828×680（旧大小）、1200×900、1400×1000。窗口大时左右栏、表格列、货架列数、K 线图（3 倍像素）、首页卡片、订单两栏、钱包表按多出的宽度放宽，文字放大到约 1.24 倍（上限 1.3，行高和商品卡同步）。
+- mod 设置（分类：界面、剧情、难度）：终端窗口大小；Tumbler 剧情开关；风险倍率（骗局、跑路、钱包投毒、地址劫持、钓鱼概率）和挖矿产出倍率，档位 ×0.5 / ×1 / ×1.5 / ×2，领域层 `Scales` 读取。分类名要等本地化表可用后再登记。
 - 多语言：新增 de fr es pl ru ja 六种语言表（连同 zh en 共 8 种，对应游戏主菜单的语言）。英文表是源文，其他语言由 Gemini 分块译出（术语表 `docs/i18n-glossary.md` 在运营仓库，游戏已有的词用官方译名），未经人工校对，文件头有说明。键集合、占位符、`§ ¶ \\n` 标记由单元测试逐语言核对，非中日语言里不得出现汉字或假名。
 - 多语言布局：表格单元、按钮文字放不下时自动缩小字号（最小 68%）再省略，商品名限定两行内缩放；de fr es pl ru 的钱包表、手册章节列表、硬件钱包粘贴键按语言放宽；ru de 等少数过长标签改短（永续“加保证金”键、收益池列头）。
 - 中文“匿名币”改称“隐私币”（英文 privacy coin），手册、黑市标签同步。

+## Settings
+
+Mod settings are in the game's mod list (select the mod, gear button); they apply to all saves.
+
+| Section | Setting | Values |
+|---|---|---|
+| Interface | Trading terminal size | 828×680, 1200×900 (default), 1400×1000. Layout and text scale with the window; applies when the terminal is next opened. |
+| Story | Tumbler storyline | on / off. Off stops new visits; progress already made is kept. |
+| Difficulty | Risk multiplier | ×0.5 / ×1 / ×1.5 / ×2 on the chance of scams, rug pulls, wallet poisoning, address hijacking and phishing. |
+| Difficulty | Mining reward multiplier | ×0.5 / ×1 / ×1.5 / ×2 on the block reward paid to the player's rigs. |
+
+## Languages
+
+The interface follows the game language: en, zh, de, fr, es, pl, ru, ja. English is the source text; zh is hand-written; the other six are AI translations and have not been proofread. Tables are in `src/Decentralized/ModFiles/Localization/<code>.csv`.
