function New-HardeningHTMLReport {
    <#
    .SYNOPSIS
    Generates a professional HTML report from markdown documentation.

    .DESCRIPTION
    Converts markdown documentation (typically COMPLETE_TESTING_GUIDE.md) into a professionally
    styled HTML report with navigation, status indicators, and responsive design.
    Creates output directory if it doesn't exist.

    .PARAMETER MarkdownFile
    Full path to the markdown file to convert. Must exist and be readable.
    Default: C:\Repos\WinHarden\docs\testing\COMPLETE_TESTING_GUIDE.md

    .PARAMETER OutputFile
    Full path where the HTML report will be saved.
    Default: C:\Reports\WinHarden\WinHarden_Testing_Report.html

    .PARAMETER WhatIf
    Shows what would happen without making changes.

    .PARAMETER Confirm
    Prompts for confirmation before generating the report.

    .EXAMPLE
    New-HardeningHTMLReport -MarkdownFile "C:\Docs\GUIDE.md" -OutputFile "C:\Reports\Report.html"

    Generates HTML report from GUIDE.md and saves to Report.html

    .EXAMPLE
    New-HardeningHTMLReport

    Uses default paths to generate HTML report

    .NOTES
    - Creates output directory automatically if missing
    - Uses UTF8 with BOM encoding per STRUCTURE.md 7.8
    - Uses ASCII-only output tags ([OK]) per STRUCTURE.md 7.10
    - No external dependencies required
    - Requires PowerShell 5.1+

    .OUTPUTS
    System.IO.FileInfo
    Returns file info object for the generated HTML report.

            <h2 id="overview">Overview</h2>
            <p>WinHarden has completed a comprehensive 5-phase testing suite covering functional, integration, end-to-end, performance, and security dimensions. All 25 test scenarios passed with 100% success rate.</p>

            <h3>Testing Pyramid</h3>
            <p>The testing approach follows a pyramid structure with 5 distinct phases, each validating specific dimensions:</p>
            <pre>
                          Phase 5: Security [OK] 5/5
                        / \
                       / Phase 4: Performance [OK] 5/5
                      / / \
                     / / Phase 3: E2E [OK] 5/5
                    / / / \
                   / / / Phase 2: Integration [OK] 5/5
                  / / / / \
                 / / / / Phase 1: Manual [OK] 5/5

CUMULATIVE: 25/25 PASS = 100% [OK]
            </pre>

            <h2 id="phase1">Phase 1: Manual Testing</h2>
            <p>Manual testing validates core functionality through direct interaction with workflows.</p>
