A progressive teaching guide (docs/fp-tea-atomic-design.md): FP fundamentals,
The Elm Architecture, and atomic design, taught Elm-then-this-app with the real
store/machine/value-object code, plus four recipes and a glossary. It owns the
teaching arc and cross-references ARCHITECTURE.md/ADR-0001 rather than duplicating
them. Documents reality where the PRD diverged (no state-debug-view feature; per-
wizard stores; reduce vs update naming) and flags the absent debug view as an open
question. Adds pointer links from ARCHITECTURE.md and CLAUDE.md.
