One encrypted settings item per account (a secure note carrying app_settings, at a fixed per-account id) holds the theme and light/dark appearance, so it syncs like any item and the server can't read it. Lists hide it; older apps see a note that explains itself. app_theme / set_app_theme in kv-ffi and kv-wasm. Also fixes a flaky test that checked random ciphertext for the letters K1.
