3.2.1

• Added a demo GIF to the README showing the raised look, the button press, and the automatic light/dark switch.
• Documented that the automatic light/dark switch needs a dynamic palette, and corrected doc comments that still described dark mode as iOS 17+ only.
• README polish: CI status badge, current install version, and a resize snippet that compiles where it's pasted.
• CI now treats Swift warnings as errors.
• Broadened the tests (settle cancellation, full press recolour, geometry, safe no-ops on unstyled views) and removed a timing-flaky test.

3.2.0

• Dark mode is now handled automatically on iOS 15–16 as well; calling refreshNeumorphicShadows() by hand is no longer needed on any version.
• Fixed a leak where re-styling a view (for example a reused cell) stacked a new light/dark observer on top of the old one.
• Added the MIT license.
• Added a CI workflow that builds and tests on every push.
• Rewrote the README in plainer language.
