     Overlay is keyed off body.sidebar-open (set by the JS toggle) rather
     than .sidebar itself, because .sidebar has a `transform`, and per the
     CSS spec, an element with `transform` becomes the containing block for
     its own `position:fixed` children/pseudo-elements — so a `::before`
     overlay attached to .sidebar can never actually cover the full
     viewport, only its own 280px-wide box. That was the real cause of the
     "sidebar looks open with no dimmed background" bug. `body` never has a
