Notes

• The caniuse widget requires JavaScript — in saved/exported HTML it is replaced by a plain link to caniuse.com
• The feature key is the slug from the caniuse.com URL: https://caniuse.com/FEATURE-KEY
• wf-* prefixed features (Baseline/web-features) are not yet supported — they come from a different data source
• To find the right feature key, browse caniuse.com and copy the URL slug
