-# Playwright Base Image for FinlyticNews
+# Shared Playwright Base Image
+#
+# Consumed by BOTH FinlyticNews/Dockerfile and FinlyticFundamentals/Dockerfile.
 #
 # BUILD ONCE (only rebuild when PLAYWRIGHT_VERSION changes):
-#   docker build -f FinlyticNews/Dockerfile.playwright-base `
-#                -t finlytic-playwright-base:1.49.0 `
-#                FinlyticNews
+#   .\rebuild-playwright-base.ps1
+# or, via Compose:
+#   docker compose --profile build-base build finlytic-playwright-base
+#
+# Not built by a plain `docker compose build` — Compose does not resolve
+# FROM-references between services, so this must exist beforehand.
 #
 # This image is then used as the base in the main Dockerfile so that
 # Chromium + all its OS dependencies are already cached in the image layer
