// The Compatibility panel detects issues by comparing against official MDN compatibility data
// at https://github.com/mdn/browser-compat-data). It uses a local snapshot of the dataset.
// This dataset needs to be manually synchronized periodically
// The subsets from the dataset required by the Compatibility panel are:
// * browsers: https://github.com/mdn/browser-compat-data/tree/master/browsers
// * css.properties: https://github.com/mdn/browser-compat-data/tree/master/css
// The MDN compatibility data is available as a node package ("@mdn/browser-compat-data").
// This node script downloads `browsers.json` and `css-properties.json` and updates the relevant files.
