v0.2.1 - README honesty and no-rounded-cards cleanup

Cuts a patch release for the README / theme.toml honesty work and the
kbd / debug-overlay / ss01 polish that fell out of the post-v0.2.0
review.

Also drops the `[X.Y.Z]: .../releases/tag/vX.Y.Z` reference-link block
under every version. Those refs anchored no prose anywhere in the file
and only mirrored metadata the tag itself already carries; for a repo
that auto-publishes Releases, the duplication had no reader who
benefited.
