This pull request intends to copy stitches since it's unmaintained. Some modifications I made:

• Improve type system
• Improve generated class
• Use the version from this pull request

I think we should not release package stitches. We should probably bundle together with fuel-ui and fuel-react.

I agree stitches packages should be private (not released) and only accessible when developing fuel-ui locally

card is looking too big (spacings and header text) is it expected and part of our design system? if not let's fix

[LuizAsFight]

even simplest card is looking too big with too much spacing

[LuizAsFight]

it's looking pretty decent @pedronauck congratz

did you test if it still works with linking locally to fuels-wallet repo ? would be nice to check

@LuizAsFight This PR isn't intended to have any changes in terms of design, it just has the fork of stitches. So, all these design specs are the same as the old version that is already published. But, of course, if this is not good we can change, but the ideal place to have this mentions should be here:
