10/// # A note on fonts
11///
12/// `Font` may differ from the everyday notion of what a "font" is.
13/// A font *face* (e.g. Fira Sans Semibold Italic) is part of a font *family* (e.g. Fira Sans),
14/// and is distinguished from other font faces in the same family
15/// by its style (e.g. italic), its weight (e.g. bold) and its stretch (e.g. condensed).
16///
17/// Bevy currently loads a single font face as a single `Font` asset.
