/*
 * Card grids, on every page (29 Sep 2026).
 *
 * What was wrong, measured over every page: a card's mark stood beside all of
 * its text, so in a row of four the words had 190px to run in and a short
 * paragraph became eight lines; a row of seven left one cell empty; and one
 * card with a thirteen-line list made its three neighbours as tall as itself
 * and mostly empty.
 *
 *   1. The mark stands beside the title only. The text under them has the
 *      whole width of the card.
 *   2. Rows are filled. The last row shares the width between the cards it
 *      has, so seven cards are four and three, never four and three and a gap.
 *   3. A card with far more to say than the others leaves the row: two cards
 *      wide, or a row to itself with its list across it in columns. Which, is
 *      decided from the copy in DocPage.tsx (shapesOf).
 *
 * .is-fill marks the grids this applies to.
