DocsContent and DocsSubsections read the guide straight from fr.json and
en.json, but their tests run on fixtures: a string where an array is
expected, a sub-section without its steps or a French list longer than
its English one only showed in the app. DocsContent.locales.test.ts reads
the real files: every section DocsContent renders and no other, the
strings and string arrays it reads, sub-sections that readSubsections
keeps whole, anchors of their own, French and English item for item, and
the path's sub-section in the section "Open the guide" opens.
DocsContent exports SECTIONS for it.
