Custom CSS theme remains referenced after being disabled and removed

What Happened?

I installed a custom CSS theme (@phenrique-coder peace-mind) and later attempted to disable it.

The theme could not be reliably toggled on/off, so I uninstalled it entirely and then reloaded the app. But that was in vain, hence closed the app. That was also no use.

So i deleted the app itself and then after reinstalling Logseq, the default theme was displayed correctly and no visual remnants of the custom theme were present.

However, inspecting the Developer Console showed that Logseq was still attempting to load the removed stylesheet:

Observed Behavior

• Logseq still attempts to load the deleted CSS file
• Console reports ERR_FILE_NOT_FOUND

Reproduce the Bug

1. Install a custom CSS theme (e.g. peace-mind)

2. Enable the theme

3. Disable or uninstall the theme

4. Restart Logseq

5. Open Developer Tools → Console

Expected Behavior

After a custom CSS theme is disabled or removed:

• No references to the theme should remain
• Logseq should stop attempting to load the CSS file
• No missing-file errors should appear in the Developer Console

No source files or tests are named. Reproduce on Mac with Logseq 2.0.1-alpha+nightly.20260527: install, enable, remove, restart, and inspect Developer Tools → Console for the deleted stylesheet request. Trace the theme removal and startup stylesheet-loading entry points, then verify restart produces no request or ERR_FILE_NOT_FOUND.
