/* ── Compare Words Overlay — scoped under #compare-overlay ───────────
   Full-screen AI comparison panel (docs/DIC-WORDCOMP.md). Opens from a
   dictionary entry or a flashcard; searches the dictionary, locks a base
   word, and renders a structured AI comparison (or a prose fallback).

   Stacking: z-index 1500 — above #dict-overlay / #flash-overlay (1000),
   below #kanji-detail-overlay (2000, kanji-detail.css). The kanji-detail
   modal reuses this screen's KanjiCards via .wd-scope (dictionary.css) —
   do NOT style .wd-scope / .detail-kanji* here.
