This is my first attempt to use Vue 3 in a FEM challenge. With this project I faced several doubts and needed to use Pinia for the modal opening buttons and I believe I'll need to use it to store the data from the total backed.

At this point I feel I'm struggling with the basics on CSS, or the scope isn't right and i'm not getting there... I need to align the modal's cards headers and for some reason I can't. If there's someone which has a better knowledge on Vue and can checkout my code, I would appreciate any feedback to improve my challenge.
