// v1.1 adds support for Stable Diffusion 2. It expands the domain scope to match other applications on HuggingFace, and includes negative prompts in the filename, with format: "'<positive>' (anti '<negative>')".
// v1.2 handles updated DOM structure of the site
// v1.3 adds support for more Huggingface spaces, including https://huggingface.co/nerijs/pixel-art-xl and https://huggingface.co/spaces/songweig/rich-text-to-image and https://huggingface.co/spaces/Yntec/ToyWorldXL
// These changes may result in false positives, i.e. unnecessary download buttons showing up. Let me know if this happens.
// Show-on-hover code is simplified (at some negligible performance cost), and this may fix some interaction issues.
// v.14 fixes detection of the prompt input (used for the download filename) for https://huggingface.co/spaces/songweig/rich-text-to-image which uses nested iframes,
// as well as some other spaces.
// It also fixes an unnecessary download button for the user-uploaded input image in https://huggingface.co/spaces/editing-images/ledits
