✅ Approved
Review Summary
Core Fix: The margin increase from 80px to 90px for macOS Tahoe (version 26+) correctly addresses the traffic light button overlap issue.
Version Check: OperatingSystem.IsMacCatalystVersionAtLeast(26) is correct - the issue specifically reports "Tahoe 26.1" which is macOS version 26.
Backward Compatibility: ✅ Maintained - older macOS versions continue to use the 80px margin.
Test Coverage: ✅ Screenshot-based verification with includeTitleBar: true properly validates the fix.
Formatting: Fixed minor formatting issues (unused import, indentation, newlines).
Note: The existing review comment suggesting version 18 instead of 26 is incorrect. Apple unified version numbers across platforms in 2025, and macOS Tahoe IS version 26.
