Changing default theme can break HTML forms generated by XB API routes: always negotiate the Stark theme

Can't get any core theme so far to break it. Perhaps there really was something exceptional about https://www.drupal.org/project/demo_design_system → ? 🤔

We'll have to figure out what.

I don't think we should spend time figuring out what in that theme is breaking this. Regardless of the reason, we should ensure the forms are rendered with a theme that is known to work. I'm wondering if we should use Stark for this? Or maybe we could use a hidden theme specifically created for this so that it's not visible through the UI.

do allow the theme to be changed?

Why would we allow that? I don't see why would anyone do this.

Yay for #4 and #5. Great.

I'm wondering if we should use Stark for this?

Let's do this. And then let's get @bnjmnm to sign off on it.

This is in the critical path for 🌱 Milestone 0.1.0: Experience Builder Demo Active — see #3454125-53: Implement temporary design system for the DrupalCon Barcelona demo → .1.4.

@utkarsh_33: there's 2 nits to address, but they aren't commit-blocking.

I did find this doesn't actually quite work yet though, for subtle/tricky reasons, and I'm not quite sure how to proceed. I think @bnjmnm has ideas around this: https://git.drupalcode.org/project/experience_builder/-/merge_requests/1...

Addressed feedbacks.

👍 Still needs final review from @bnjmnm.

Stressing the importance

Brute force Stark as a dependency is fine.

Great! I wasn't entirely confident that this made sense from a semi_coupled.engine POV — so great to have your +1 😊

Needs final sign-off from a BE reviewer. It's late in the European day, so asking @tedbow.

Actually … I think @bnjmnm's sign-off alone is more than sufficient. No need to succumb to CODEOWNERS as an iron first.

This helps accelerate 📌 Implement temporary design system for the DrupalCon Barcelona demo Needs work , so bypassing approval for this MR…
