+<!-- 
+    This helper method converts paths that are relative to the repository's working directory to a Hugo mount folder.
+    Paths that do not start with '/' are returned as-is. The prefix of an absolute path is truncated if it matches
+    either with the page bundle folder (starting with "/content/"), the assets folder ("/assets/"), or the static
+    folder ("/static/").
+    
+    The partial supports the following arguments:
+    "path"          Required path of the resource, e.g. "/assets/img/example.jpg".
+    "page"          Required page context, used to identify page bundle resources.
+-->

+{{ $path := .path -}}
+{{ $page := .page -}}
+{{ if hasPrefix $path "/" }}
+    {{ $pageContext := (path.Join "/content" $page.File.Dir) -}}
+    {{ if hasPrefix $path $pageContext }}
+        {{ $path = strings.TrimPrefix $pageContext $path -}}
+        {{ $path = strings.TrimPrefix "/" $path -}}
+    {{ else if hasPrefix $path "/assets/" }}
+        {{ $path = strings.TrimPrefix "/assets" $path -}}
+    {{ else if hasPrefix $path "/static/" }}
+        {{ $path = strings.TrimPrefix "/static" $path -}}
+    {{ end }}
