//! Unit tests for Windows capability/permission probing (sibling of `capabilities.rs`).
//!
//! These exercise real, live checks against this machine (DXGI output
//! enumeration, WASAPI endpoint enumeration, WGC contract query) — not just
//! pure logic — so most assert on the *shape* of the result (e.g. "not the
//! not-implemented case") rather than a fixed value, since dev machines vary
//! (a screen-less CI runner has no DXGI output; a muted/absent mic still
//! enumerates as a valid endpoint or not depending on driver).
