-# Logging helpers and Write-LogHybrid fallback
+.SYNOPSIS
+    Core logging utilities for SAMY.

+.DESCRIPTION
+    Provides:
+      - Write-LogHelper  : standalone logger with console, file, and Event Log support.
+      - Write-LogHybrid  : wrapper that prefers toolkit Write-Log if present, else falls back.
+
+    This module is loaded first so that other subsystems can safely call Write-LogHybrid.
