 - Adds a CSS view helper that enables the rendering of a `noscript` variant and allows inline styles to be replaced by a key-value-based `inlineReplacements` option flag
 - Adds a sentry middleware and frontend module ...
 - Adds a custom TYPO3 page renderer template which removes some unnecessary spaces and changes the order of inline CSS injection
+- Adds a backend avatar provider that assigns the move elevator logo to backend users with an `@move-elevator.de` email address (when no custom avatar is set)

+### Backend Avatar
+
+The `MoveElevatorAvatarProvider` automatically assigns the move elevator logo (`Resources/Public/Icons/me.svg`) as the backend avatar for any backend user whose email address ends with `@move-elevator.de`.
+
+Personal avatars uploaded via the user settings always take precedence — the logo is only used as a fallback when no custom avatar is configured.
