The Order of the Seder

It is appropriate to set out for ourselves an order for the seder night:

The descriptive text in this haggadah seems almost as if it says that הלל is the fulfillment of הלל נרצה, as one unit. Perhaps not. Though the piyutim at the end of the seder are a later insertion and are not mentioned by e.g. the Tur, this Haggadah does have a section of piyutim in the back.
