+.SYNOPSIS
+    Benchmark Issue_Files: convert user-reported xlsx/docx to PDF (MiniPdf + LibreOffice) → compare → report.
+
+.DESCRIPTION
+    Converts files in tests/Issue_Files/xlsx and tests/Issue_Files/docx using both
+    MiniPdf and LibreOffice, then runs compare_pdfs.py to produce a comparison report.
+
+.EXAMPLE
+    .\scripts\Run-Benchmark_issues.ps1
+    .\scripts\Run-Benchmark_issues.ps1 -SkipReference
+    .\scripts\Run-Benchmark_issues.ps1 -CompareOnly
