/* Worth Memorizing. The form comes from the thing itself: a ruled index card and the
   card box that spaced review was invented with. BibleDo law: Fraunces for Scripture
   and headings, Inter for our words; gold is light (the card's header line, the glow
   where a word was), never a surface; clean white by day, true black by night. */
