@userquin I would also love to have https://github.com/user-attachments/assets/29e796ae-6c84-4cf7-8328-b846e3df1f35 in "Running Tests" section - could you help me with that? (need dark mode)

So, now the only way to access the browser mode page is from the navbar, maybe we can add the link in the left aside. On mobile the browser mode link will be on top right menu and missing from the left menu hamburger button.

(just add the Browser Mode link without expandable children)

My logic was that it is still displayed in the right hamburger on mobile. Isn't it enough?

It is fine, no other entries in the navbar present.

FYI: maybe we can remove mastodon, X and discord links from resources navbar menu, already present in the navbar

@userquin @JessicaSachs made iframe scalable (similarly to how cypress implements it) - please check when you have time 🙏🏻

Note: I didn't change the viewport reset yet, it's a bit tricky (it won't be changed in this PR)

Oof, I forgot about the "Select a test to run" use case 👀

from the ui?

[userquin]

The ui doesn't start, Vitest hangs when running nr test:browser:preview or any other provider.

LGTM

Remember to update images for Vitest ui and coverage (6 in total, 3 per theme): /guide/ui.html and /guide/coverage.html#vitest-ui pages
