/* Sidebar TOC: bold section/chapter-level entries, light grey only for entries nested
   two levels deep (true subchapter pages). MyST's book-theme sidebar gives every depth
   the same .myst-toc-item class; nesting is only expressed structurally via
   .collapsible-content wrappers, so depth has to be targeted that way rather than
   through a dedicated class. A single level of nesting (e.g. appendix's flat list of
   pages under "Setup and reference", or a Part's chapters) reads the same as the
   top level; only a second level of nesting (e.g. 1.1, 1.2, ... under a chapter) grey. */
