function clsx(value) {
	if (typeof value === 'object') {
		return _clsx(value);
	} else {
		return value ?? '';
	}
}
Small wrapper around clsx to preserve Svelte's (weird) handling of falsy values.
TODO Svelte 6 revisit this, and likely turn all falsy values into the empty string (what clsx also does)
@param  {any} value
