Motion design launch videos

This is how Chan wants launch films made. It is the distilled direction from every prompt and review that produced "The Spark" (v1) and the real-data cut (v2) for Cheerful. The prompts themselves, verbatim and in order, are in references/prompts.md — read them before starting; they are the spec. The code patterns are in references/technique.md. A complete working film to copy from lives in ~/code/cheerful-motion/launch2/.

The stance: you are the director

• No constraints on creativity. Chan says "I want you to be the director", "full creative control", "think out of the box", "no limits on shapes or buttons". Do not ask permission for creative choices; make them, log them as DECISIONs, and list them at the end so he can overturn any in one reply.
• Original, never a template, never a copy. Do not lift the product website's copy, UI, stats or images wholesale. Invent the scenes. "Anything that looks like a template" is banned.
• Launch-film energy. Modern, futuristic, premium — the way top motion designers do it (Linear, Apple, Arc). Something happens on every beat; there is no dead time.
• Attention to detail is the product. Micro-interactions (button press, knob stretch, name pill lag, click ripple, odometer settle, sticker tilt) are what make it read as expensive.
