Illustrated Explainer Spec Implementation Guide

What This Project Is

A spec (not a library) for building a locally-run single-page web app where:

1. User types a topic → AI generates a 16:9 watercolor-style illustrated explainer page
2. User clicks anywhere on the image → AI generates a "drill-into" next page for that spot
3. This repeats infinitely, preserving painting style across all pages
4. Content-addressed caching means identical queries/clicks never re-generate

The spec is stack-agnostic — you choose the framework, image model API, and language. This skill shows you how to implement it end-to-end.
