Clean testimonials (clear dev/test entries + dedupe) and show each reviewer's language; pre-warm the voice

Pre-warm the voice on app entry so audio is ready sooner

Home page with sliding testimonials, full 5-language i18n across the whole UI, animated solar background, rating capture from all users, responsive pass

Full app: user accounts (signup/login), per-user sizing history, admin usage dashboard; local /data storage (durable via persistent storage), self-managed keys, no exposed credentials

Off-brand: bespoke custom frontend (FastAPI + hand-built HTML/CSS/JS) replacing the Gradio surface; reuses the engine, generators, 3D scene and models
