# A vegan adaptation of a classic bechamel: the recipe's cow's milk is swapped for oat milk.
# The substitution specification has as its parts the recipe it amends, the two transformations
# it prescribes, the objective of the swap, and the three conditions under which it holds.
# One individual of every class the pattern declares, wired up as its restrictions prescribe.
