function Export-RemediationPlaybook {

    <#

    .SYNOPSIS

        Generates a step-by-step remediation guide grouped by category and priority.

    .DESCRIPTION

        Produces an HTML playbook organized into phases (critical first, then high, medium, low).

        Each finding includes prerequisites, step-by-step remediation, validation steps,

        effort estimates, and cost tier information.

    .PARAMETER Findings

        Array of audit finding objects. If not provided, reads from latest state.

    .PARAMETER OutputPath

        File path for the HTML output. Default: PSGuerrilla-Remediation-Playbook.html

    .PARAMETER OrganizationName

        Organization name for the report header.

    .PARAMETER MaxCostTier

        Maximum cost tier to include. Default: Medium.

    .EXAMPLE

        Export-RemediationPlaybook -OrganizationName 'Springfield USD'

    .EXAMPLE

        Export-RemediationPlaybook -MaxCostTier Free -OutputPath ./free-fixes.html
