/*
 * Amordle updates.
 *
 * The tokens below are lifted from the game's own shell (src/app/tui-shell.css
 * and src/app/globals.css) rather than approximated, so this site and the game
 * are the same object seen from two places. The type scale is the game's six
 * steps, the spacing scale its seven, and the rules, prompts and hanging
 * markers are the ones the app uses.
 *
 * Hand-written CSS on purpose. A changelog that needs a build step to publish a
 * paragraph is a changelog that stops getting written.
