/* ============================================================
   The Lexicon board (Nina, 2026-08-05)

   Every entry on this page is already a comparison, so the card is
   split down the middle: two terms, two colours, one card. The split
   does the teaching before anyone reads a word.

   Continues the Diary's material language (app/blog/blog.css): same
   cream paper, the same five brand hues at paper weight, same slight
   rotation. Pins rather than tape and a dark board rather than journal
   paper, so this reads as its own surface and not a copy of /blog.

   Loaded only by lexicon.html, after assets/styles.css, so the brand
   tokens from :root there resolve and are used directly.
