+# The browser end-to-end suites, one job per browser, deliberately not part
+# of the check workflow. REPO_POLICIES.md caps make test at 20 seconds and
+# script/cibuild is a plain `docker build .` whose Dockerfile runs
+# make check; folding a browser suite into either would break that cap and
+# slow the local fast path. These jobs are the automatic run the suites
+# never had: before this workflow, every browser-level guarantee in the
+# repo held only when a human remembered to run it by hand.
+#
+# One job per browser rather than two steps in one job, so a Chrome failure
+# does not hide the Firefox result.
+#
+# These jobs REPORT, they do not gate: nothing merges or refuses to merge on
+# their result by itself. Gitea decides that in branch protection, which
+# this repo does not set, so a failure here is a red mark the reviewer must
+# account for rather than a hard block. Making e2e a required check is the
+# right end state and is deliberately not done yet, because the Chrome
+# suite is flaky today under load (see the tracker) and a gate that fails
+# at random teaches people to merge past red.
+#
+# Nothing here is allowed to pass vacuously. There is no continue-on-error
+# and no `|| true`: script/test-e2e and script/test-e2e-firefox both exit
+# non-zero when docker is missing, when the extension build is absent, and
+# when the browser fails to start, and the Chrome harness aborts the whole
+# suite if its network interception is not in effect.
