+Feature: #108580 - Improved page module content preview
+=======================================================
+
+See :issue:`108580`
+
+Description
+===========
+
+The page module's content element preview functionality has been
+enhanced to provide editors with a better visual representation of content
+elements in the backend.
+
+Sanitized HTML rendering for content
+------------------------------------
+
+Content elements with HTML in the bodytext field (such as text, text & images)
+now display sanitized HTML in the page module preview instead of plain text.
+
+A new :php:`\TYPO3\CMS\Core\Html\PreviewSanitizerBuilder` has been introduced that creates a sanitizer
+specifically for backend previews. This sanitizer:
+
+*   Removes clickable links (unwraps :html:`<a>` tags while preserving
+    their content)
+*   Removes heading tags (:html:`<h1>` through :html:`<h6>`) while
+    preserving their content
+*   Allows safe HTML formatting (bold, italic, lists, etc.)
+
+Enhanced bullet list preview
+----------------------------
+
+Content elements of type "bullet list" now render as HTML lists in the preview.
+
+Harmonized menu element rendering
+---------------------------------
+
+Preview rendering for menu content elements and "insert records" elements
+has been harmonized to match the layout used in the record selector wizard.
+This provides a consistent experience across different parts of the backend.
+
+Impact
+======
+
+These enhancements improve the editorial experience in the TYPO3
+backend by providing clearer, more informative content previews. Editors can now:
+
+*   See formatted HTML content as it will appear to users
+*   Quickly identify bullet list structure and content
