Description

I'm following along learning Svelte but it's a bit disconcerting that something as important as theming doesn't seem to be working properly in your educational course. I don't want my websites switching themes unpredictably. This bug has happened on numerous pages, I decided to report it on the latest one it's happened on. I'm going to assume it's something wrong with the tutorial rather than Svelte. It happened when I clicked the login button here:

Contributor guide

Research direction
Investigate the theme toggle implementation on the Svelte tutorial site. Check how the dark/light mode preference is stored (localStorage, cookie, etc.) and how it is applied on page load and after actions like login. Look for inconsistencies in the theme state persistence across navigation or after state changes.
