product-video은(는) 무엇을 하나요?
Create a short premium product video (Remotion + React/TypeScript) from software that already exists in the repo — launch video, landing-page hero, demo reel, feature announcement. Works for web apps, mobile apps, CLIs, APIs and SDKs, desktop apps, extensions and data products. Clarifies scope first, then derives everything on screen from the repo rather than inventing it. Use when asked to make a product video, demo video, launch video, feature video, or to "record a demo" of something in this
