docs(wiki): rewrite Home.md to full 14-section visual-first template
- Banner updated to c84dd78 / 2026-05-11
- Section 2: add diffuser (data.otr path, not child-register), upstream
reactor stateChange, settler downstream; switch to ~~~mermaid fences
- Section 4: accurate code-map — cstr/pfr extend baseEngine, not peer nodes
- Section 6: split measurement into temperature + oxygen(PFR) rows; clarify
diffuser is NOT a registered child; switch to ~~~mermaid fences
- Section 7: expand sequence with n_iter formula, DO capping, GridProfile alt
- Section 9: correct timeStep unit note (schema h vs HTML label s), add all
13 init fields, note X_A HTML default footgun, enum-casing note in cell
- Section 14: add row #6 (reactor_type enum lowercasing / toUpperCase guard)
and row #7 (timeStep unit mismatch — label vs schema vs engine conversion)
AUTOGEN markers (topic-contract, data-model) untouched — regenerated clean.
