/* ─────────────────────────────────────────────────────────────────
   IELTS Speaking — Phrase Toolkit.

   Library-style reference design (NOT a drill). Warm pearl theme.
   Each category carries its own --cat-accent which colours the
   left strip, icon background, deep-dive star, and CTA link. The
   landing is a 2-column grid of 10 category cards; the category
   page groups phrases into sub-sections; the deep-dive page is
   a single-phrase article with quote block + usage list + why-it-
   works callout.
