/**
 * Per-site contact form configuration — per-subdomain contact pages.
 *
 * Pure module — imports NOTHING from solid-js / @solidjs/router / @solidjs/meta —
 * so it can be unit-tested in `bun:test` without spinning up the router / Meta
 * provider, mirroring the testability pattern established by `page-head-meta.ts`
 * and `nav-config.ts`.
 *
 * The shared `<ContactForm>` (`src/components/ContactForm.tsx`) reads the active
 * `site` via `useSite()` and derives its `subjectPrefix`, recipient label,
 * heading copy, and PageHead description from this map. Call sites may still
 * override these defaults via props (e.g. to inject a site-specific subline or
 * render a `children` block such as the Life-and-Lineage Q&A accordion).
 *
 * Email routing contract:
 *  - `subjectPrefix` is the bare prefix token placed in front of `" Contact
 *    Request"`. The main site keeps `"freno.me"` (no brackets) so the existing
 *    `"freno.me Contact Request"` subject is byte-identical after the refactor
 *    (backwards compatibility for any inbox filters / saved searches). Each
 *    product subdomain uses a bracketed token (`"[Nessa]"`, `"[Lineage]"`,
 *    `"[Gaze]"`, `"[InputHalo]"`) so inbound mail can be
 *    routed / triaged by source product.
 *  - All mail is delivered to `michael@freno.me` (single owner across every
 *    product); `recipientLabel` is a display-only affordance, not an alternate
 *    SMTP recipient.
 *  - The tRPC `misc.sendContactRequest` mutation and the no-JS server action
 *    both receive this prefix and emit the identical subject — a single source
 *    of truth lives here.
