/* Day theme. Follows the system appearance.
   --trace stays #C9EB2E and --focus stays var(--ember-ink):
   both are identical in Day and Night.

   Lime and white do not go together. --trace on the Day paper is 1.2:1
   and on a white card 1.4:1, which is unreadable, so in Day the brand
   lime is a fill colour only: buttons, the lime panel, the numbered
   circles. Lime text uses --trace-ink, 6:1 on the Day paper and 6.8:1
   on a white card. Night reads the same, because --trace-ink is the
   lime there. Run tools/check_contrast.py to re-measure. */
