# Validates the combination of on_demand and count_on_hand values.
#
# `on_demand` can have three values: true, false or nil
# `count_on_hand` can either be: nil or a number
#
# This means that a variant override can be in six different stock states
# but only three of them are valid.
#
# | on_demand | count_on_hand | stock_overridden? | use_producer_stock_settings? | valid? |
# |-----------|---------------|-------------------|------------------------------|--------|
# | 1 | nil | false | false | true |
# | 0 | x | true | false | true |
# | nil | nil | false | true | true |
# | 1 | x | ? | ? | false |
# | 0 | nil | ? | ? | false |
# | nil | x | ? | ? | false |
#
# This module has one method for each invalid case.
