 *   the user brings only an API key. Model defaults to
 *   {@link LAYAHOST_DEFAULT_MODEL}.
 * - `jev`: Jev's own API ({@link JEV_DEFAULT_BASE_URL}) by default, or any
 *   Jev-compatible endpoint as an override URL; the model comes from the
 *   provider's `GET /v1/models` listing.
 *
 * A profile that keeps the preset URL stores the literal `default`
 * (T12733), resolved here at call time.
 *
 * The URL and model literals live in `@cleocode/contracts` (const data); this
 * module only arranges them.
