     *     headers, both required. Not Basic, not Bearer.
     *  2. **Form-urlencoded body** — `application/x-www-form-urlencoded` (most
     *     modern SMS providers use JSON). All numeric narrowed-input fields are
     *     stringified explicitly; booleans encode as `'1'` / `'0'` (Textmagic's
     *     documented expectation), not `'true'` / `'false'`.
     *
     * Wire-key casing is camelCase, written explicitly (no
     * `transformKeys` invocation). The recipient field is `phones` on the wire
     * (Textmagic supports comma-separated multi-recipient on this field);
     * single-recipient v1.0 baseline maps `input.to` → `phones` verbatim.
