Thanks for this!

I see that this includes quite a lot of themes and seems to take inspiration from other themes - could you please elaborate on what your extension adds on top of the themes it is based off? Thanks!

[SergoGansta777]

Thanks for the thoughtful review.

This extension is inspired by existing theme families, but it is not a direct re-publication.
What it adds is a consistent Hybrid/Blurred refit layer across the collection, including: palette retuning for the blurred/hybrid visual style, Zed-specific UI + syntax token remapping, contrast/readability balancing for practical editor use, unified variant curation so different theme groups feel coherent in one pack.
Attribution to original authors is preserved directly in each theme JSON. For example: "author": "neanias (Hybrid/Blurred refit by SergoGansta777)"
