+[KAS] by [@dhardy] is a general purpose UI toolkit; its
+initial aim is "old school" desktop apps with good keyboard and touchscreen
+support. Unlike many modern immediate-mode UIs, KAS's widgets retain state,
+allowing minimal per-frame updates. KAS supports embedded WebGPU graphics now,
+and plans to support embedded usage and additional rendering systems.
+
+[KAS-text] v0.2 saw a significant revision to its API, including support for
+rich text (bold, italic, underline, size and some layout improvements).
+[KAS] v0.6 pulls in those changes and adds a few fixes and QoL improvements.
