[Bug] Page styles bleeding into displayed components

[luchillo17]

Describe the bug
The components that should display the changes being done to the theme are being affected by the base theme of the page: https://github.com/jnsahaj/tweakcn/blob/main/app/globals.css

To Reproduce
Steps to reproduce the behavior:

1. Grab any component with a border in any example theme, see how the input borders are affected by CSS at the page level and those are not included in the theme code.

Expected behavior
I expected the theme being modified to be sandboxed, so the general theme of the TweakCN page doesn't affect the examples and the theme being edited.

Screenshots

My theme in the page:

My theme in my app:
