What is the source of my form button styling?

I am having trouble using the new form editor. I created a form, and set some styling parameters there.

When I add that form to a landing page, the styling is overriden by something in my theme or global settings? There are on-page styling options for the form, but it is not respecting those selections.
There is a tooltip that says “To edit this form, visit the Forms Editor” - but that takes me to where i originally configured the form, and it doesn’t respect those parameters either.

I want to change the background color and width of the button and use my custom brand font. I am a marketer and would like to be able to customize the styling within the CMS instead of adding style sheets or anything.

If your form button styling isn’t behaving as expected, check the following sources: your theme’s CSS, any custom styles applied via inline styles or external stylesheets, and any JavaScript that might be modifying the appearance dynamically. If you’re using a framework like Bootstrap or Tailwind, the default classes might be overriding your styles. Have you inspected the button using browser dev tools to track where the styles are coming from?
