WalkthroughThe frontend adds a standalone Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The new 503 page can redirect users to an external site through a crafted refresh target, and its refresh behavior is not exercised by the end-to-end test. Reject protocol-relative targets after normalization and add navigation coverage before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Exercise the refresh action in the E2E test.
This assertion checks only button visibility. It does not invoke the button, so a broken window.location.assign or window.location.reload path can still pass. Click the button with a safe from path and assert the resulting URL. Also cover the reload branch if it is part of the required behavior.

Reject protocol-relative paths after URL normalization.
/503?from=/..//evil.example can serialize to //evil.example, which window.location.assign treats as an external host. Reject targets that start with // and add a regression test.
