/* EGA-specific sidebar tweak (not ported from SGA).

   mdBook numbers every SUMMARY entry with a single continuous counter. On EGA's
   nested, section-numbered tree that renders as noisy, redundant prefixes —
   e.g. "28.1. §14. Combinatorial dimension…" or "24. Front matter". The
   installment part-titles, the "Chapter N —" group headings, and the "§N."
   labels already carry every meaningful number, so the auto-counter adds only
   confusion. Hide it; keep the labels. */
