+/**
+ * Life and Lineage contact page (`lineage.freno.me/contact`).
+ *
+ * Thin wrapper over the shared `<ContactForm>` (task 09). Site awareness —
+ * subject prefix `[Lineage]`, recipient label, heading, and PageHead metadata
+ * — is derived from `useSite()` inside the component via
+ * `CONTACT_CONTEXT.lineage`.
+ *
+ * Renders the Life-and-Lineage FAQ accordion (re-imported from the main-site
+ * contact route so the canonical definition lives in one place) above the
+ * form — the lineage subdomain is the natural home for product support Q&A.
+ *
+ * vercel.json rewrites `lineage.freno.me/*` → the internal `/lineage/*` route
+ * prefix; the browser URL stays `lineage.freno.me/contact`.
+ *
+ * Acceptance: `lineage.localhost:3000/contact` renders the contact form with
+ * Life and Lineage branding; submissions email `michael@freno.me` with subject
+ * `[Lineage] Contact Request`.
