/* === BEGIN AE-LOGO-CONTRAST (David t165u fade-to-white) ===
   Preview only. Colour logo slowly fades to vivid white (and back) when
   contrast against what is behind it drops below ~4.5:1. On light surrounds
   a solid local shade plate sits behind the mark (no surround glow). tm fades too.
   White layer uses a hard opaque white PNG. Never set height on the colour img —
   keep .logo / .footer-logo sizes so the mark cannot blow up into a watermark. */
