     The supplied logo ships on an opaque near-white canvas, which is hidden
     by `mix-blend-mode: multiply` on the mark -- white multiplied by the
     ground IS the ground. That identity only holds where the ground is one
     colour: against the soft radial wash this page used to carry, the same
     blend produced a visibly darker rectangle around the logo. The old dark
     theme's green glow and CRT scanlines were decoration; this is a
