+"""009: ship a single WebView engine (AXPR AosmiumWebView only).
+
+The AOSP/Lineage `webview` prebuilt (~255 MB) is added by
+build/make/target/product/media_product.mk, which is inherited later than
+vendor/sunfish-a16/apps.mk, so a PRODUCT_PACKAGES filter there has no effect.
+Remove the package from the media_product list instead.
+
+The provider allowlist (config_webview_packages.xml) still declares
+com.android.webview and the Google providers, so they can be installed and
+selected later; they are simply not preinstalled.
+
+Idempotent: guarded by a marker comment.
