//! Integration tests for [`sopsy::enclave`].
//!
//! Real Secure Enclave identity generation requires Apple hardware and user
//! interaction, so these drive a **fake** `age-plugin-se` shell script injected
//! via the `SOPSY_AGE_PLUGIN_SE_BIN` environment variable. That env var is
//! process-wide, so the tests are `#[serial]`.
