The reference field now accepts a single photo OR a folder of photos (face, 3/4, full-body...). With a folder, the analyzer builds an identity centroid (mean face embedding) for a much more robust 'right person / wrong person' check. New 📁 folder picker; preview shows first ref + count; no-face refs are skipped. Body-shape matching stays out of scope (face识别 via InsightFace; CLIP body sim stays indicative).
