    Anti-Fingerprinting

    • Fix Date constructor epoch for historical sub-minute LMT offsets
    • Harden prototype detection resistance (method shorthand wrapping, stack trace cleanup, synchronous iframe patching)
    • Strip console output from production builds (fixes extension name leak)

    Internal
    • Modularize injected script into 15 ES modules (still bundled as single IIFE)
    • Expanded property-based test suite for fingerprint consistency

    Other
    • Lower minimum Firefox version to 140
    • Add Waterfox build script and Chrome Web Store assets
