Persistent design rules (captured to memory)

Always end batch turns with AskUserQuestion multiSelect popup
Never pass functions from Server Components to Client Components — extract pure helpers to /lib
Sibling dynamic route segments must use identical param names
Programmatic SEO requires hand-curated content per page — not auto-generation
<img> tags require width/height attribs for CLS — pair with CSS width:100%; height:auto

Full catalog markdown lives at ~/Documents/reusable-functions-catalog.md — 10,000+ lines documenting every component, route, lib file, and gotcha.
