+> frequently sit at DIFFERENT lines (WNBA DK 21.5/FD 18.5), so it renders EACH book's own

+> (`BOOK_CROWN_ENABLED=false`); no books → NULL (self-hide). Display-only: only the

+> untouched (web-only, grade byte-identical trivially). Freshness equal (same snapshot as
+> the lock; intraday touches neither). HELD: push-to-book, movement strip, crown enable.
