/**
 * computeInscribedRect — resolve the largest axis-aligned rectangle that
 * fits entirely inside the non-black (coverage) region of a stitched
 * panorama, via native `BatchStitcher.computeInscribedRect`.
 *
 * Used to SEED the post-capture crop editor (`RectCropPreview`): instead of
 * a blind 8 %-inset rectangle, the editor opens on the max-inscribed rect —
 * the tightest clean rectangle with no black corners — which the user then
 * fine-tunes.  Best-effort: callers fall back to the default inset seed if
 * the native module is absent or the call rejects.
 *
 * Same native module + defensive-availability posture as
 * `src/stitching/cropQuad.ts` and `src/quality/normaliseOrientation.ts`.
 * The native side (Android `BatchStitcher.computeInscribedRect`, iOS
 * `OpenCVStitcher.computeInscribedRect`) is the exact `maxInscribedRectFromMask`
 * port used by the opt-in auto-crop, so the seed matches what that crop would
 * pick — only here the user can then drag outward to keep more content.
