/**
 * LLM provider presets for `viewer.agentConfig()`. These are plain data —
 * the agent core is provider-agnostic (one OpenAI-chat-completions protocol
 * over primitive `url`/`headers`/`apiKey` connection fields), so a
 * "provider" is just a spreadable collection of those fields:
 *
 * ```javascript
 * import { providers } from "@perspective-dev/viewer";
 * viewer.agentConfig({
 *     ...providers.anthropic,
 *     apiKey: "sk-ant-...",
 *     model: "claude-haiku-4-5",       // spread order = override order
 * });
 * ```
 *
 * Any OpenAI-compatible service works without a preset — pass its full
 * chat-completions `url` (and `apiKey`/`headers` as needed) directly.
 * Cloud presets call the provider from the browser tab; suitable for local
 * development, or route `url` through your own proxy for production.
