Explain Diff

Turn a code change into a rich, interactive learning artifact — not a passive summary. The reader gets oriented, builds intuition, walks the code, then actively checks their understanding with a quiz. The design is grounded in learning science; the principles are named inline where they apply, and citations are in ATTRIBUTION.md.

Adapted from Geoffrey Litt's explain-diff prompts (see ATTRIBUTION.md).
