v0.1.91

The pictures show what ships. The floating keyboard in the README, and every screenshot in the store listing, were captures from before the keys were redrawn — hold hints outside the key faces, a layout key that did not say where it goes, a space bar labelled with a word. They are rendered from the current code now, over a page of writing rather than a blank ground, because a translucent panel over nothing looks solid.

No behaviour changes in this one.

Reproducibility re-verified at this tag under JDK 21.
