/* The word list and the word page. Loaded after shell.css, which owns the
   design tokens, the reset and the tab bar.

   TWO LAYOUTS, ONE MARKUP. On a wide screen the list is a six-column table;
   under 760px each row folds into a two-line card, because six columns at
   375px gives every one of them about 50px and the definition — the reason
   you are reading the row at all — becomes an ellipsis. The fold is a CSS
   grid-template change, not different markup, so there is one render path.

   The row height differs between the two, and the list is virtualised, so JS
   has to know it: --row-h is read back by words.js. Change it here only. */

   toolbar and the count strip. It differs per breakpoint because the toolbar
   wraps differently and the nav bar moves to the bottom. */
