 * Mirrors Google's canonical snippet: `function gtag(){dataLayer.push(arguments)}`.
 *
 * Pushing `arguments` rather than a plain array is not a stylistic detail.
 * Google's tags recognise a consent command by the Arguments object it arrives
 * in; a real array lands in the dataLayer as ordinary data and the command is
 * silently ignored — the tag loads, but consent never updates and analytics
 * stays denied. The rest parameter exists only to type the call sites.
 *
 * Exported for the analytics module (which needs `js`/`config` commands) —
 * intentionally not re-exported from the package's public API.
