1//! The Bern icon set: icon names in SF Symbols naming. The Apple targets
2//! draw every SF Symbol; the other targets map each name to one of their
3//! platform's own icons, and every one of them draws at least the names
4//! listed here. A name a target cannot draw fails its check at the
5//! element, so no target shows a placeholder in its place.
