- Install rehype-slug (proper heading anchors) + github-slugger (matching TOC) - TOC component: auto-generated from h2/h3 headings, clickable anchors - Dark mode toggle: ThemeToggle (localStorage + system default), class-based - /docs index page (lists all docs by section) - Markdown.tsx uses rehype-slug for stable heading ids - globals.css: @custom-variant dark (.dark class) for class-based dark mode - layout.tsx: nav includes ThemeToggle Note: per user instruction, installed real deps (rehype-slug, github-slugger, @types/hast) instead of hacky inline any-cast hacks.
