Release 1.3

versionCode 4. public_html/ changed, so the service worker cache goes to

The five store screenshots are untouched: the ring only exists while a finger
is on the button, and none of them shows that.

+around the button fills while you hold it, and springs back if you let go
+early, so the button explains itself. A short sound confirms the reset when
