If you would read your own Catechism closely you will see that ultimately all is considered Grace

2011 The charity of Christ is the source in us of all our merits before God. Grace, by uniting us to Christ in active love, ensures the supernatural quality of our acts and consequently their merit before God and before men. The saints have always had a lively awareness that their merits were pure grace.

Thus, there can be no human works involved, since it is all of grace by your own definition. (Rom.4:4)

If it is all of grace than it must all of faith (4:16)

Human response is not considered a 'work' since it does not entail any human merit on the part of the responder, he is but yielding to grace (Rom.6)

[annalex]

Now to him that worketh, the reward is not reckoned according to grace, but according to debt (Rom 4:4)

Indeed, works done for economic or social reward do not count for salvation.
