/**
 * The single, provider-agnostic {@link PhotonAIProvider}. It is driven entirely
 * by a consumer-supplied {@link PhotonAIProviderConfig}: pick a hosted
 * {@link PhotonAIProviderType} for out-of-the-box defaults (endpoint, model,
 * auth, wire format), or override any field — up to and including the full
 * request/response wire format via `requestTransformer`/`responseTransformer` —
 * to talk to any JSON HTTP model endpoint.
 *
 * Uses the native `fetch` API only (no SDK), so it runs in every browser Photon
 * Grid supports. The API key is read from config at request time and applied
 * with the provider's auth scheme; it is never hard-coded, cached, or logged.
 * Every failure mode — HTTP errors, rate limits, auth problems, safety blocks,
 * timeouts, and malformed JSON — surfaces as a categorized
 * {@link PhotonAIProviderError}.
