   Read in the evening, in a dim room, next to a lit lamp, at arm's length,

   that: warm dark ground, large type, high contrast on the current line only,
   and tap targets sized for a hand that is busy. */

   kept for the one navigation cue, Next up. Text is off-white on a dark
   ground at about 12:1: pure white on near-black blooms (halation) at night.
   Festive colour lives only at the edges and in the one highlight; the text
   column always sits on flat colour. */
