C — git-revision-date-localized plugin: adds a 'Last update' date to every V2
page (freshness signal for SEO and reader trust). Added the dependency to
requirements.txt, enabled it in v2-mkdocs.yml (type: date,
fallback_to_build_date so the build never fails), and set fetch-depth: 0 on the
06 deploy checkout so the plugin sees full git history (otherwise every page
would show the build date).
D — JSON-LD schema.org structured data: WebSite (with a sitelinks SearchAction)
+ publishing Organization, injected via an extrahead block in docs/overrides/
main.html (shared V1/V2). Enables richer search results / knowledge-panel
eligibility. Validated: build exits 0, JSON-LD parses, 'Last update' renders.
