   Sidebar TOC toggle: pin the expand/collapse caret to a fixed,
   centered position at the top-right of each entry, instead of
   letting it fall inline with (and get pushed around by) the
   link text. Ported from the ThinkPy sidebar fix (_static/shared.css),
   with `white-space: nowrap` deliberately dropped — this book
   allows long titles to wrap to a second line rather than
   forcing them onto one (see book-authoring SKILL.md, "Title
   Length"), so the link text must stay wrappable.
