Bulk Upload Stimuli via File Browser

Researchers can now select and upload multiple media files at once through the file browser, instead of uploading each stimulus one at a time when building a study. This makes setting up a study with several stimuli noticeably faster than before.

If the number of files selected goes over the maximum supported stimulus limit, the platform now automatically uploads only the permitted number and skips the rest, rather than failing the entire upload. Researchers get a clear notification showing how many files were successfully uploaded and how many were skipped, so there's no confusion about what actually made it into the study.
