Signature, parameters, and return type

/**
 * Non-throwing probe: can this runtime render the given zone?
 *
 * `'UTC'` and `'device'` are always true (no Intl involved). For an IANA name it
 * runs the same checks the formatters run and returns false instead of throwing,
 * so an app can decide its own policy once at boot — e.g.
 * `const zone = canFormatTimeZone('Asia/Seoul') ? 'Asia/Seoul' : 'UTC'`.
 *
 * Results are cached: the runtime-wide Intl self-test runs at most once, and each
 * zone is checked at most once. Repeated calls are a map lookup.
