/* Book Summary. Two colour jobs matter more than the rest of the sheet:
 *
 *   - a confirmed fact and an unverified fact must be distinguishable at a
 *     glance and WITHOUT colour, because the difference between them is the
 *     whole point of the app. Both carry a word, not just a hue.
 *   - a false citation must not read as a slightly worse version of unverified.
 *     It gets the alert treatment, a border and a full sentence, because it is
 *     the failure this app was built to surface. */
