design

Design system funnel — 5 verbs: define · destructure · adjust (freeze 3-layer contract) · enforce (portable linter + sc-* pivot + 3 gates) · diffuse (elements under gate + sc-* pivot). Adds copycat (per-page mockup→contract reconciliation agent + Python fidelity oracle: machine CLOSED/OPEN verdict, structural completeness scan, coverage guard, deviation-ledger with id + registry validation, ledger-unused detection, active-frame isolation, check_text per-target P7+P11, collections LCS-diff P8+P12, Windows stdout P10, collection-level ack P13, visual-diff companion P14). Adds config-gen.py (P15): auto-derive oracle config from contract — components.json BEM selectors + tokens.json prop groups → targets+props+breakpoints, with oracle hints per component. Breaking: replaces 9 legacy skills.
