How nfty works

Background, not instructions. Read these when you want to know why nfty behaves the way it does -- away from the work, rather than in the middle of it.

• The six words

  ---

  CookBook, Recipe, Ingredient, Variant, Set, Kitchen. Learn these and you have learned the app.

• Why layers are drawn in gray

  ---

  The single idea the whole product is built on.

• The three kinds of layer

  ---

  Dynamic, Static and Custom, and how to choose.

• How uniqueness is decided

  ---

  What a fingerprint is made of, and why the count is a promise rather than an estimate.

• Why a seed reproduces a collection

  ---

  What is guaranteed, what is not, and what breaks it.

• What sealing does and does not do

  ---

  The encryption is real. The view-only mark is a lock on a door, not a wall.

• Why nfty never resizes your art

  ---

  The refusal that looks unhelpful and is not.
