+echo "Skip Chromium's new first-run EULA on machines already on Quattro"
+
+# Chromium 151 flipped MasterPrefs::eula_required from false to true, so an
+# unconfigured first run now stops on a blank terms-of-service dialog before the
+# browser opens. Omarchy answers that in the seed it writes next to the Chromium
+# binary, but that seed is only laid down by a fresh install and by the one-time
+# 3.x upgrade, so machines already on Quattro never receive it. Retrofit it here.
+#
+# The literal is deliberately duplicated rather than sourced: a migration repairs
+# the state of its own moment, and must not drift when the seed later changes.
