Navigation and Layout

The default layout mirrors VitePress docs structure:

• fixed top nav
• left sidebar groups (collection-driven)
• main content area
• right outline synced to h2/h3

Sidebar entries are generated by vp_theme.sidebar_collections and each collection’s nav_order.

vp_theme:
  sidebar_collections:
    - id: getting_started
      text: Getting Started

Use layout: home for landing pages where sidebar and local nav should be hidden.
