HeaderBar's centre region defaults to centring on the whole bar's own width, regardless of how wide the leading/trailing regions actually are — search floated visibly off from NavigationSidebar's own right edge as a result. CENTER_LEFT switches it to fill the entire leftover span instead, left-aligned within it; a dynamic left margin then places it exactly at NavigationSidebar.TOTAL_WIDTH. Margin is computed from the brand's actual bounds, not from pholio.css's own header padding: on macOS, HeaderBar also reserves leading space of its own for the native traffic-light buttons, which that padding alone doesn't account for and which disappears in fullscreen.
