The previous commit collapsed both header spans into a single isMobile-
conditional render, but that broke 3 desktop-header tests that
intentionally assert on both spans being present (the CSS handles
visibility). The real fix for the "Found multiple elements" failures
was the localStorage.clear() in beforeEach; the structural change was
unnecessary. Restore the original dual-render markup.
