 *
 * - `debug` → `console.debug`
 * - `info` → `console.info`
 * - `warn` → `console.warn`
 * - `error` → `console.error`
 *
 * When a `meta` object is supplied it is rendered with the strategy that
 * actually surfaces it on the current runtime (see {@link MetaStrategy}):
 * depth-unlimited `console.dir` on Node, circular-safe JSON on Cloudflare
 * Workers, and an extra console argument everywhere else.
 *
 * This is the logger used when `debug` is enabled on any activity and no
 * custom `logger` is supplied via `debug: { logger }`.
