A part page's parent is its last crumb and is marked in the sidebar.
A Next steps link pointing back in the reading run gives way to the run
order, so Start here reads every page once.
The decoration pass now forwards the logo front matter, pointed at the
local copy. The emulators index lists every profile under the initial
the sidebar draws, so each letter link lands on its section.
The 404 page opens on Start here instead of tabs numbered 0 to 4. A group label is a group, or in Explore one link to its overview, never a link to its first page, and a crumb names the section that introduces the page. Emulators sit one level deep by initial. Previous and next run within a tab (Start here into Your setup) and skip system, emulator and platform pages, and follow a page's Next steps list. Reference pages group under Checking files and Data, a wiki page joining by its group: front matter. redirects.json maps alternative core names to their profile.
generate_site.py --engine starlight writes the pages, navigation and
data files of an Astro Starlight project in website/. Links resolve to
site addresses, every heading keeps its MkDocs id, and pages split by
size are measured in the MkDocs Markdown so both builds cut the same
files. The 839 pages and their 45,613 ids match the MkDocs build.
