// FilamentServiceProvider.php

ViewComponent::macro('warningHint', function (\Closure|bool|null $condition, \Closure|string|null $message): static {
    return $this->hintIcon($condition ? 'heroicon-c-exclamation-triangle' : null)
        ->hintColor('yellow')
        ->hintIconTooltip($message);
});
