Debounced (400 ms) automatic language detection across 110 languages (up to five candidates with name + ISO code + confidence) that runs once typed text reaches 10 characters with no button press, plus a two-text cosine-similarity comparison via the on-device MediaPipe text embedder. Fully on-device; models download only when typing crosses the auto-detect threshold or Compare is pressed. Regrouped from ui/blocks/vision-lab (Language tab) into a new standalone text category (roadmap D2 — NOT merged into text-insights).
