Turn the demo into a parametric portfolio prototype

[terpjwu1]

Summary

• evolve the single-demo experience into a portfolio homepage concept built around a live Pretext hero
• keep the animated parametric text displacement, but frame it as a ClawDogLab portfolio with selectable motion systems
• add manifesto, selected work, process, and contact sections so the interaction reads like a product direction for a personal site

Testing

• npm run build
• npm run lint
• npm run dev -- --host 127.0.0.1
