/**
 * nativeUltraWide — decide whether to offer the "open the OS camera for 0.5×"
 * affordance on a device whose ultra-wide is unreachable in-app.
 *
 * WHY THIS EXISTS: on some Android devices (proven on the Samsung Galaxy A34,
 * SM-A346x) the ultra-wide is a **system-only** physical camera — invisible
 * and unopenable to any third-party app (`getCameraCharacteristics` throws
 * `Unknown camera ID`; `getCameraIdList` omits it). `selectCaptureDevice`
 * correctly returns `has0_5x=false` (no in-app 0.5×), and there is NO Camera2
 * path to recover it. The only way an operator can capture a 0.5× shot on such
 * a device is the OEM camera app (which has privileged access). This helper
 * gates a "0.5× ⤢" fallback affordance that hands off to that OS camera.
 *
 * Pure + host-agnostic. The affordance is shown only when ALL hold:
 *   - platform is Android (iOS virtual devices already span the ultra-wide;
 *     the fallback is never needed there),
 *   - the in-app pick found NO ultra-wide (`hasInAppUltraWide === false`), and
 *   - the running device's model/manufacturer matches the host-supplied list.
 *
 * The list is host-supplied (see `<Camera nativeUltraWideModels>`) — the
 * library ships no device knowledge; the consuming app maintains which models
 * hide the ultra-wide.  An empty/absent list disables the feature entirely
 * (default OFF).
