Casual \"Labubu-toy\" visuals (dusk-purple / misty-blue gradients, cream sticker panels, retro keyboard). No build, no install — just open `index.html`.\n\n**English**\n\nA typing trainer for keyboard beginners, built with vanilla HTML/CSS/JS (no frameworks, no dependencies). It bundles a lesson path plus four mini-games that work together:\n\n- 🎯 **18 progressive lessons** — standard touch-typing teaching order (FJ → DK → SL → … → sentences with Shift practice), with a live virtual keyboard, finger-color hints, and a **music mode** that turns the keyboard into a piano (6 public-domain melodies).\n- 🎵 **Rhythm Mode** — a falling-note rhythm game: hit the right key as notes cross the judgement line and the melody plays; 6 songs on a gentle 55→100 BPM ladder, beginner-friendly timing windows, S/A/B/C ratings.\n- 🏎️ **Typing Race** — a 1000m sprint over 30 words: correct words push you forward, mistakes push you back; race a ghost car paced at your own best WPM (beating it ≈ setting a new record).\n- 💣 **Bomb Defusal** — type 3 sentences (capitals + periods) against a 90-second countdown, one wire per sentence; live left/right-Shift hints make case mistakes self-explanatory.\n- 🛡️ **Keyboard Defense** — a 5-lane tower-defense mini-game where you type to kill incoming enemies; combos, perfect-defense bonuses, and per-hero score multipliers keep it addictive.\n- 🏆 **Heroes & Ranks** — collect 5 heroes (each unlocks a wider letter pool and a score multiplier) and climb 6 rank tiers (Bronze → King) measured in 🏆 trophies earned from lessons and mini-games.\n\nEverything (sound effects, enemy visuals, virtual keyboard) is synthesized at runtime with WebAudio + CSS/emoji — **no image or audio assets**, fully playable offline via `file://`.\n\n面向键盘初学者的英文盲打训练网页游戏。拉布布潮玩风：暮紫灰 → 雾蓝渐变底 + 细波点，奶油贴纸面板，奶油白复古主机键盘 + 悬浮白键。\n\n## 运行方式\n\n纯原生 HTML/CSS/JavaScript，零依赖、零构建。**双击 `index.html` 即可离线运行**（file:// 协议）。\n\n## 文件结构\n\n```\nKeyboardHero/\n├── index.html 单页多屏（div 切换 display）\n├── css/style.css 主样式（潮玩主题、虚拟键盘、塔防战场、动画）\n├── css/rhythm.css 节奏模式样式\n├── css/bomb.css 拆弹专家样式\n├── css/race.css 打字赛车样式\n├── js/data.js 段位表、英雄表、关卡数据、单词表、短句表、歌曲曲库\n├── js/app.js 界面切换、主菜单、指法图解、闯关训练、英雄选择、战绩页\n├── js/battle.js 键盘保卫战（五路塔防）\n├── js/rhythm.js 节奏模式（打字版太鼓达人）\n├── js/bomb.js 拆弹专家（倒计时剪线）\n├── js/race.js 打字赛车（竞速）\n├── specs/ 模块规格书与协作约定\n└── README.md\n```\n\n## 玩法说明\n\n游戏由主线 + 小游戏 + 成长体系组成：**闯关训练负责系统学习，节奏模式 / 打字赛车 / 拆弹专家三个小游戏按「字符 → 单词 → 短句」分阶巩固，键盘保卫战负责实战爽感，段位与英雄收集负责长期动机。**\n\n### 闯关训练（18 关，标准盲打教学顺序）\n\nFJ → DK → SL → A;
