Cadence is a focused interview practice recorder built with Next.js + Tailwind CSS, Gemini, and TwelveLabs.

• Open Cadence and pick a question to practice.
• Hit record, answer out loud, then stop when you're done.
• Review the transcript and scores, then retry or download your clip.

• Records interview responses and stores clips locally in the browser.
• Uses Gemini to transcribe, score technical correctness, and count long pauses + filler words.
• Uses TwelveLabs to score delivery confidence with concise feedback.
• Lets you review results, retry a question, and download or delete clips.
