Voice-to-text transcription with live recording visualization - shadcn/ui

Voice recorder with a solid circular primary mic button (orange idle, red while recording) with subtle ping rings, a centered symmetric waveform of thin rounded bars animated by layered sine functions (smooth motion, no random jitter), and a mono recording timer. The transcript streams in word by word with a blinking cursor into a bordered text surface (not a textarea), followed by Copy (emerald check feedback), Clear, and a right-aligned translate group with target language select. Translation appears in a muted surface with entrance animation. Source language select lives in the card header.
