+    .SYNOPSIS
+        Generates a simple, readable slug (alias) from input text.
+
+    .DESCRIPTION
+        Converts a string into a URL/alias-safe slug:
+        - Lowercases everything
+        - Replaces spaces/underscores with dashes
+        - Removes invalid characters
+        - Collapses multiple dashes
+        - Ensures max length (default: 16 chars) cutting at the nearest dash if possible
+
+    .PARAMETER InputString
+        The text you want to convert into a slug.
+
+    .PARAMETER MaxLen
+        Maximum allowed length of the slug (default: 16).
+
+    .EXAMPLE
+        New-Slug "Hello World! This is an Alias"
+        # hello-world
+
+    .EXAMPLE
+        New-Slug "Daily Check In" -MaxLen 12

+    $slug = $slug -replace '[\s_]+', '-'      # spaces/underscores → dash
+    $slug = $slug -replace '[^a-z0-9-]', ''   # keep only alphanumeric/dash
+    $slug = $slug -replace '-{2,}', '-'       # collapse multiple dashes
+    $slug = $slug.Trim('-')                   # remove leading/trailing dashes
+
+    if ($slug.Length -gt $MaxLen) {
+        # Try to cut at the last dash before max length

+        if ($lastDash -gt 0) {
+            $slug = $cut.Substring(0, $lastDash)
