Set up React Router (HashRouter) for multi-page docs navigation,
react-markdown with remark-gfm and rehype-highlight for rendering
markdown content with syntax highlighting, and @tailwindcss/typography
for prose styling. Add DocsLayout with collapsible sidebar, MarkdownPage
component with Vite glob imports, and docs-nav.ts for sidebar structure.
Configure Vite base path for GitHub Pages deployment.
