Each file is a details whose summary is the row: name, folder when it is not the bare name, status chip. The short hash sits on one copy button beside it, since a summary is itself a control. Opened, the evidence runs across the list. A list with no folder drops the column. Code spans in the evidence are plain text. The lists split by the share of a page they render to (elements against 10,000, bytes against 600,000) instead of Markdown length. With its parts, Batocera goes from 12 pages, 18,854 elements and 1.21 MB to 10 pages, 13,671 and 1.11 MB. A part that folds back into its platform page redirects there, from the record in website/src/data/platform-parts.json.

"""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
