/* ============================================================
   Letters (/letters/, /letters/<slug>/, /letters/confirm/<token>; routes/letters.js)
   Loads AFTER tb-baekja.css; tokens only. The letters page's one gold is the
   subscribe button; a letter page's one gold is its "Get the letters" link;
   the confirm card's one gold is its button. Newsreader is latin-only, so every
   serif stack carries Pretendard before the generic serif.
