Describe the bug

The page header shows that the Chroma Playground has an outdated version, nominally 2.9.1, released in September 2023, almost a year ago.

As a consequence, the Playground may behave differently from the latest version. For instance, some tokyonight themes from #957 have not been loaded into the page, as shown in the image below.
