What is inside
  • Three layers Asset pipeline, engine and method: what each does and where it lives in the repo.
  • 20 examples How to run them locally and which six to try first.
  • BRIEF-TEMPLATE.md A one-page brief: brand, signature interaction, hero object, sections, must-be-true.
  • PROMPTS.md Six prompts: read the engine, re-theme, build from a brief, review loop, ship, one new asset.
  • Real costs What is free, what needs fal credit, and the author’s own cost figures.
  • Honest catches GPU load, Google Fonts in the examples, GSAP licence, fictional brands.

Git, Node.js 20+, about 1 GB of disk and a computer with a decent GPU. Running and re-theming the examples is free. New 3D models need your own fal API key and fal credit (paid). Claude Code or another coding agent for the prompts. The guide is in English.
