+# Speedometer 3.0: Terminal Emulator (Xterm.js)
+
+## Description
+
+This workload simulates an interactive developer terminal environment using [xterm.js](https://xtermjs.org/) and its official addons (`@xterm/addon-fit`, `@xterm/addon-web-links`, `@xterm/addon-canvas`, and `@xterm/addon-webgl`).
+
+## Implementation Details
+
+The application maintains four distinct terminal sessions organized into tabs (`Build Log`, `Links & Traces`, `Ncurses Monitor`, and `Git Status`). To ensure deterministic timing and repeatable results during benchmark runs, the workload incorporates universal asynchronous overrides (`async-overrides.js`) that intercept and synchronize `setTimeout`, `requestAnimationFrame`, `createImageBitmap`, and DOM observers (`ResizeObserver`, `IntersectionObserver`, `MutationObserver`).
+
+### Benchmark Steps
+
+1. **Dump & Scroll Output**: Dumps ~75 chunks (~750+ lines) of verbose C++ compilation logs into the viewport, exercises scrolling operations, and simulates user selection across blocks of output.
+2. **Parse & Hover Inline Links**: Emits test logs saturated with URLs and file paths, then dispatches synthetic mouse hover events across grid cells to trigger regex link matching and decoration updates (`@xterm/addon-web-links`).
+3. **Ncurses Color UI**: Sequentially renders 4 dynamic frames of an `htop`-style system process monitor using cursor positioning, RGB TrueColor escape sequences, and partial buffer refreshes.
+4. **Switch Tabs & Resize**: Simulates switching active terminal tabs and resizing panel widths to trigger column reflow calculations (`@xterm/addon-fit`).
+
+## Build Steps
+
+The workload uses Vite to bundle dependencies into the `dist/` folder:
+
+```bash
+npm install
+npm run build-dev
+```
+
+## Local Preview
+
+To run the application in development mode with live reloading:
+
+```bash
+npm run dev
+```
