/* Ivory & Ash.
   Ivory Ash #e7eae0 · Chalk #f0f2ec · Slate Sage #d5d9cc · Lichen #c8ccbf
   Deep Space Blue #153243 · Harbour #5a7d90 · Ash Grey #b4b8ab.

   Ivory Ash is the ground the page is read on. Deep Space Blue is the ink and
   the primary: headings, buttons, bars, focus rings — anything that has to be
   seen at a hairline's width. Ash Grey is the mark, and only ever a fill:
   it sits at 1.66:1 against this ground, which is a highlighter's job, not a
   signal's, so it goes behind text (the block in the headline, a selection, a
   struck link) and never becomes text, a rule or a ring. Whatever the mark
   fills carries --mark-tx on top of it, which clears 6.6:1.

   Dark is the same families with the ground and the ink swapped, and there the
   mark and the primary coincide — Ash Grey is legible on Deep Space Blue, so
   it does both jobs. Dark is opt-in: the toggle below sets data-theme and
   nothing else does, so ivory is what a visitor lands on. */
