What

The description for upload_asset, part of the Artifact tool, now explicitly lists stylesheet (CSS) and script (JS) files as types of local files you can upload as an asset, in addition to the previously listed images, videos, PDFs, fonts, and text formats.

Why

This makes clear that CSS and JS files are supported for upload, which matters when working with artifacts that need their own stylesheets or scripts alongside other assets.
