   IELTS Writing — Phrasebook styles.

   Mirrors the visual shape of sp-phrase-toolkit.css (the Speaking
   parallel) without sharing class names: prefix `wr-pb-` so the two
   tools can evolve independently. Cream-theme tokens come from the
   IELTS v2 shell — body.has-ielts-nav sets --ielts-* on the body.
