-# Rebuild the Playwright base image for FinlyticNews.
+# Build the shared Playwright base image (Chromium + Node + Playwright CLI).
 #
-# Run this script ONLY when you update the Playwright NuGet package version.
-# After running this, a normal `docker compose build` will be fast again.
+# CONSUMERS — both reference this image as `FROM finlytic-playwright-base:<ver>`:
+#   * FinlyticNews/Dockerfile
+#   * FinlyticFundamentals/Dockerfile
+#
+# This image is NOT built by `docker compose build` (Compose does not resolve
+# FROM-references between services). It must exist locally BEFORE building
+# those two services, otherwise their build fails with "pull access denied".
+#
+# Equivalent Compose route (same image tag, declared in compose.yaml):
+#   docker compose --profile build-base build finlytic-playwright-base
+#
+# Run this ONLY when the Microsoft.Playwright NuGet version changes
+# (see FinlyticCore/FinlyticCore.csproj) — otherwise the cached layer is reused.
