 * A centered, rounded card floating on a neutral background. A Washington, DC
 * background photo (chosen per-login by season/holiday, see LoginBackgroundBean)
 * fills the card and blends via a left-to-right dark gradient into a form panel on
 * the right that holds the sign-in controls. The panel keeps its own translucent
 * dark backing so the form stays legible over any photo.
