Rendering Baseline statuses with `web-features`

If you're using web-features to render Baseline iconography or browser logos with support markers, then you must follow the name and logo usage guidelines.

For Baseline iconography, follow this procedure for each feature:

If status.baseline is "high", then show an affirmative "widely available" icon.
If status.baseline is "low", then show an affirmative "newly available" icon.
If status.baseline is false, then show a "limited availability" non-Baseline icon.

Note: All features that have the discouraged property are, by definition, non-Baseline, and status.baseline will be false. If a feature has the discouraged property, consider showing a message describing the feature's discouraged status instead of Baseline iconography. Showing Baseline iconography for discouraged features may confuse readers.
If status.baseline is undefined, then do not show any Baseline or non-Baseline badge.

For browser support iconography (that is, browser logos and checkmarks and Xs), follow this procedure for each browser:

If status.baseline is "high" or "low", then show a green checkmark (✅, "supported") beside each browser's logo icon.
If status.baseline is false and the browser's status.support key (for example, status.support.edge) is undefined or false, then show a gray X ("unsupported") beside the browser's logo icon.
If status.baseline is "high" or "low" and the browser's status.support key is a string, then show a green checkmark ("supported") beside the browser's logo icon.

If you wish to report browser version numbers, avoid showing version numbers alone. Developers and users often do not know whether a version number refers to a very recent or old release. If you must show a version number, consider contextualizing that number by showing a release date, a relative date (such as "Released … years ago"), an offset (such as "… releases ago"), or usage statistics relevant to your audience (such as "…% of your visitors in the last 90 days").
