Extra Tips included or expected?

The few TA sites I've seen indicate that Ponant cruises are gratuities included.

Reading through the FAQs yesterday, I noticed that the FAQs in French are a lot more detailed than in English and German. Among them was this one which is not n the English or German FAQs:

Les pourboires sont-ils obligatoires ?

La gratification au personnel fait partie des usages à bord des navires de croisière et est laissée à votre appréciation. Une enveloppe anonyme est mise dans votre cabine en fin de croisière. Vous pouvez la déposer ensuite à la réception dans une urne prévue à cet effet. Cette récompense libre est généralement de l’ordre de 10 à 12 € par jour et par passager. Elle est répartie, ensuite, entre les membres de l’équipage.

Which translates (as good as my French is):

Are tips obligatory?

Gratuities to crew are left to your discretion. An unmarked envelop is left in your cabin at the end of the cruise. You can leave in an urn by the reception. This tip is generally in the order of €10-12 per pax per day and is shared among members of the crew.

The other stuff pertains to animals, kids, laundry services, electricity and languages.

It's optional, but I have always left a tip for my cabin steward and an additional crew tip via credit card. It's not much in the scheme of things.

I think it may depend on which country you book from. My Ponant invoice includes this line:

TIPS FOR ALL INCLUSIVE USA

That makes me think that other countries will have different inclusions.
