+Slint 1.17 pins line height to the requested font's ascent, descent and leading,
+but StyledText does not expose line-height. This metrics-only font supplies 1.5em
+line boxes without replacing any visible glyphs: Slint's normal system fallback
+fonts still render the text and links. Use this family for message and release-note
+bodies without changing the typography of other controls.
