终端 TUI 系统监控界面

一张全屏终端 TUI 系统监控应用截图，使用经典 ncurses 风格框线字符绘制面板。左上「示例应用」面板：八核心横向块字符进度条；右上「内存」面板：内存使用条「已用：11.2 GB / 16 GB」；中央宽幅「进程」列表表格，列名为「进程号、名称、CPU%、内存%、状态」；底部「网络」面板：上传「↑ 上传 2.4 Mb/s」和下载「↓ 下载 18.7 Mb/s」ASCII 折线图。配色黑色终端背景、亮绿色 #00FF41 主文字和进度条，等宽位图字体，地道终端美学。CPU、GB、Mb/s、ASCII 可作为技术缩写和单位保留；不要英文列名、英文按钮、真实系统标志、水印或乱码。

A realistic screenshot of a terminal-based text UI (TUI) system monitor application running in a dark terminal window at full screen. The layout resembles classic ncurses-style panels drawn with box-drawing characters (┌─┐│└─┘). Top-left panel: "CPU Usage" — eight horizontal bar graphs, one per core, made of block characters (█░░), percentage labels on the right. Top-right panel: "Memory" — a single large bar showing "Used: 11.2 GB / 16 GB", a smaller swap bar. Center-wide panel: "Processes" — a scrollable list table with columns PID, Name, CPU%, MEM%, State (R/S/Z) for 15 rows of realistic process names ("node", "chrome", "postgres", "kernel_task", etc.). Bottom panel: "Network" — two sparkline ASCII graphs labeled "↑ Upload 2.4 Mb/s" and "↓ Download 18.7 Mb/s" drawn with braille or underscore characters. Color palette: black terminal background, bright green #00FF41 for primary text and bars, dim green for secondary, white for column headers. Monospaced bitmap font. Authentic terminal aesthetic.
