A setup's list for one console is a reference page kept out of the search index, naming its setup as parent. System pages carry file names and the platforms' own ids as attribute search fields, never as text. Arcade gets its own sidebar group.

"""The site as an Astro Starlight project: pages, sidebar and data files.
|
|
|
|
generate_site.py writes each page body, and this module gives it the form
|
|
Starlight reads. A page's links are written as the docs tree holds them
|
|
(``../systems/sony.md``, MkDocs' convention, the one a Markdown editor
|
|
follows), and the site serves them as addresses under /retrobios/, so
|
|
each target is resolved against the page's own place here. Every heading
|
|
keeps the id the MkDocs site gave it, so the anchors cited since stay

valid.
