Technical Specifications

Build a high-performance, agency-grade Tabs section called "Technical Specifications" in React 19, TypeScript, and Tailwind CSS with Framer Motion.

## 1. Overview & Visual Objective
Build a Stats section for an aerospace company called "EngineTech." This is a dark-background section with a two-column header, a 4-tab switcher, and an animated horizontal bar chart with range indicators, spark traces, and staggered entrance animations. The tab switching re-renders the chart with new data and replays all animations.
