/* Hue marketing page.
   Colour-blind friendly by construction: all text is neutral white/grey on near-black
   (≥ 7:1), no state or meaning is carried by hue alone (pressed buttons get a check mark
   and an inverted fill, swatches always carry a name), links are underlined, and every
   swatch has a light outline so its edge reads under any type of colour vision. */
