 * How loudly the SDK reports handled failures to the console.

 * - `error` (default) — `console.error`, exactly as before.
 * - `warn`   — `console.warn`, for apps whose crash reporters treat
 *              `console.error` as a signal.
 * - `silent` — no console output at all. `handleError` still returns the
 *              composed message, so callers that surface it in the UI are
 *              unaffected.

/**
 * Sets the SDK's error log level.
 *
 * **A bare setter, deliberately — not a `SublayProvider` prop.** The setting is
 * process-global (`handleError` is a plain function imported by ~60 modules; a
 * per-call-site option would mean touching all of them), and this codebase
 * explicitly supports two providers being mounted at once. A prop would read as
 * per-provider while silently being last-mount-wins, and would not restore on
 * unmount.
 *
 * Coarse by design: it silences *all* SDK logging, unexpected failures
 * included. There is no per-condition severity, because the call site usually
 * cannot know whether its own failure was expected.
 *
 * ```ts
 * import { setSublayLogLevel } from "@sublay/core";
 * setSublayLogLevel("silent");
 * ```
