-.SYNOPSIS
-    Generates a WAV audio file from text using Windows built-in TTS.
-
-.DESCRIPTION
-    Uses System.Speech.Synthesis.SpeechSynthesizer (built into Windows — no
-    external API key or installation required) to convert a narration string
-    into a WAV file.
-
-    Called by the Playwright screenshots spec after each page.screenshot() call
-    so that every blog screenshot has a matching narration audio file.
-
-.PARAMETER Text
-    The narration text to speak. Keep to 1-3 sentences for best pacing.
-
-.PARAMETER OutputPath
-    Full path for the output WAV file (e.g. screenshots-output\series-1\dashboard.wav).
-    Parent directory must already exist.
-
-.PARAMETER Voice
-    Optional. Name of an installed Windows TTS voice.
-    Run: Add-Type -AssemblyName System.Speech; (New-Object System.Speech.Synthesis.SpeechSynthesizer).GetInstalledVoices() | Select -ExpandProperty VoiceInfo | Select Name
-    Defaults to the system default voice.
-
-.PARAMETER Rate
-    Speech rate: -10 (slowest) to 10 (fastest). Default: -1 (slightly slower
-    than default for clearer narration in video).
-
-.PARAMETER Volume
-    Volume: 0-100. Default: 100.
-
-.EXAMPLE
-    .\speak.ps1 -Text "The dashboard loads immediately after login." -OutputPath "screenshots-output\series-1\dashboard.wav"
-
-.EXAMPLE
-    .\speak.ps1 -Text "Here we can see the AI insights card." -OutputPath "out.wav" -Voice "Microsoft David Desktop" -Rate -2
