+  # Lighthouse CI drives a real Chrome via chrome-launcher, which
+  # probes the PATH / CHROME_PATH for a standard Chrome/Chromium
+  # binary. The Playwright image bundles Chromium under /ms-playwright
+  # with a non-standard name chrome-launcher cannot discover, so we
+  # stay on the base Node image and apt-install Debian's `chromium`
+  # (lands at /usr/bin/chromium). The future ADR-0016 axe-core e2e job
+  # — which drives Playwright directly — will use the Playwright image
+  # instead: the two tools want different things, so they get
+  # different images rather than one image that serves both poorly.
