Subject: [PATCH] Add "Cookie preferences" to the docs About nav
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Docs pages are rendered by the landing app (landing clones this repo into pages/docs
and its docs layout wraps the shared shell), so they already load PostHog via #1165 —
but docs has no footer for the "Cookie preferences" withdraw control. Add it to the
firecracker nav's About section (next to Privacy Policy / Terms) as a hidden
`#footer-cookie-prefs` anchor that posthog-consent.js un-hides + wires for in-scope
visitors. Rendered only when POSTHOG_API_KEY is set at build time.
