/*
 * FIX: Sidebar was visually dominating the page because the TOC
 * had no height cap and 26+ items pushed everything else down.
 * Solution:
 *   1. Narrow the sidebar slightly (240px vs 280px).
 *   2. Cap the TOC list at ~320px and make it independently
 *      scrollable so it never overflows the viewport or crowds
 *      the main content.
 *   3. Keep sidebar sticky so the TOC stays accessible while
 *      reading without blocking the article.

 * Users can scroll within the TOC to see all 26 items.
