+The `selenium-devtools-latest` artifact is a stable alias that republishes the protocol classes of
+`LATEST_CDP_VERSION` under the `org.openqa.selenium.devtools.latest` package. Users who don't want
+to update their imports on every Chrome bump can write:
+
+```java
+import org.openqa.selenium.devtools.latest.page.Page;
+```
+
+The alias artifact contains only the generated protocol types; the runtime `CdpInfo` registration
+is provided by the versioned `selenium-devtools-v<LATEST>` artifact, which is pulled in as a
+transitive Maven dependency. The alias is rebuilt automatically when a new CDP version is added — no
+extra steps are required when bumping `CDP_VERSIONS`.
