fix: v1.4.2

1. 填了模型路径后红色线框变橙色(已更改标记)
   - setParam时实时更新线框样式，保留焦点不重建DOM
2. 二进制程序区域宽度缩小一半，运行模式区域扩大

+# 🦙 llama.cpp 命令生成器
+
+> 一个用于生成 llama.cpp 执行命令的 Web 工具，支持参数可视化配置、自然语言生成、实时显存估算。
+
+## ✨ 功能特性
+
+### 命令生成
+- **多版本支持**：内置 b6310 和 b10068 两个版本的参数定义，可按版本精准匹配参数
+- **GPU 模式 / GPU+CPU 模式**：默认 GPU 模式，可切换混合模式查看系统内存占用
+- **多 GPU**：最多支持 4 张显卡，每张可选不同型号，自动计算总显存
+- **智能输出**：仅输出非默认值的参数，生成干净可用的命令
+
+### 自然语言生成
+输入自然语言描述，自动解析为参数配置：
+
+```
+用RTX 4090跑70B模型, 上下文8192, 温度0.7, flash attention
+```
+
+支持中文和英文关键词，涵盖 GPU 型号、数量、上下文、温度、Top-K/P、线程数、端口等。
+
+### 实时显存估算
+- 选择模型和 GPU 后实时计算显存占用
+- 分项显示：模型权重 / KV缓存 / 计算开销 / CUDA开销
+- 进度条颜色预警：绿(正常) → 黄(警告) → 红(超限)
+- GPU+CPU 模式额外显示 CPU 侧权重和 KV 缓存占用
+
+### 参数管理
+- 参数按分类标签页组织：通用 / 采样 / 服务器 / 模型来源 / LoRA / 日志 / 高级
+- 重要参数直接显示，次要参数点击展开
+- 影响显存的参数标记 ⚡ 标识
+- 支持参数搜索（按键名、标志、描述）
+
+### 模型选择
+- 内置 26 个常见模型预设（Llama 3/3.1、Qwen2.5、DeepSeek V2/R1、Mistral、Gemma2、Phi-3、GLM-4 等）
+- 支持搜索过滤
+- 后台可增删改
+
+### 后台管理
+- **GPU 管理**：增删改查显卡型号、显存、计算能力
+- **版本管理**：增删改查 llama.cpp 版本
+- **参数管理**：按版本增删改查参数定义
+- **模型管理**：增删改查模型预设
+- **系统设置**：修改管理密码等配置
+
+## 🚀 部署
+
+### 环境要求
+- Python 3.8+
+- Flask
+- flask-cors
+
+### 安装
+```bash
+cd llama-cmd-gen
+pip install flask flask-cors
+```
+
+### 启动
+```bash
+python3 app.py
+# 或
+./start.sh
+```
+
+服务默认监听 `0.0.0.0:16052`。
+
+### 访问
+- **主界面**：`http://<host>:16052/`
+- **后台管理**：`http://<host>:16052/admin`（需密码登录，默认 `admin123`）

+- **前端**：原生 HTML / CSS / JavaScript（无框架依赖）
+- **数据**：SQLite 本地存储，包含 GPU、版本、参数、模型等表
+
+## 📝 版本历史
+
+- **v1.1.0** — 修复输入焦点丢失、加参数搜索、模型选择器、后台密码登录、复制兼容性
+- **v1.0.0** — 初始版本：命令生成、自然语言解析、显存估算、多 GPU、后台管理
