/* Sign-in and sign-up screens.
   Split layout: the left panel carries the product story (a Meta reviewer
   lands here too), the right panel is the form. Below 860px the panel
   collapses to a compact header so the form stays above the fold on a
   phone — most page administrators sign in from one. */
