    🔑 Source Code: https://github.com/os9sur/MiraTranslator/
    🔑 Core Commitment: Fully open-source, decentralized, zero intermediate servers.
    🔑 Security Standard: Security should not rely solely on platform status, but on real-time audits by the global community. Our code is 100% transparent.
    🔑 Traffic Transparency: We encourage technical users to monitor data flow via DevTools (Network panel). Beyond your configured APIs, there is absolute zero background data uploading. Strict extension isolation ensures your local config remains inaccessible to malicious websites.

    🔹 Positioning: Mira Translator acts as a pure translation caller and rendering container. We do not sell keys or hijack traffic.
    
    【 🛠️ Core Technical Specs: Professional Precision 】
    🔹 Universal Web Parsing: Leverage frontier AI models to process X.com, developer docs, and official sites with native fluency.
    🔹 Shadow DOM Penetration: Resolves translation blind spots in complex web apps while maintaining perfect original layouts.
    🔹 Domain-Level Control: Customize translation areas for any site using the Visual Picker, with domain-specific strategy memory.
    🔹 YouTube Integration:  Leverages native CC logic for seamless bilingual subtitles with real-time UI preview. Supports one-click download of original or bilingual subtitles for offline study.
    🔹 Contextual Lookup: Quick lookup popup with pronunciation. Double-click subtitle words for deep semantic analysis and save to vocabulary.
    🔹 Smart Word Highlighting: Automatically highlights words from your vocabulary list on any webpage you browse. Review words effortlessly as you read, truly achieving "learning through reading."
    
    【 💡 Quick Start 】
    1️⃣ Instant Experience: Selection translation and YouTube bilingual mode are enabled by default.
    2️⃣ Enable Advanced AI: Enter your API Key in settings to experience unreservedly powerful AI translation.
