+/**
+ * InputHalo contact page (`inputhalo.freno.me/contact`).
+ *
+ * Thin wrapper over the shared `<ContactForm>` (task 09). Site awareness —
+ * subject prefix `[InputHalo]`, recipient label, heading, and PageHead
+ * metadata — is derived from `useSite()` inside the component via
+ * `CONTACT_CONTEXT.inputhalo`, so this route needs no explicit props.
+ *
+ * vercel.json rewrites `inputhalo.freno.me/*` → the internal `/inputhalo/*`
+ * route prefix; the browser URL stays `inputhalo.freno.me/contact`.
+ *
+ * Acceptance: `inputhalo.localhost:3000/contact` renders the contact form
+ * with InputHalo branding; submissions email `michael@freno.me` with subject
+ * `[InputHalo] Contact Request`.
