The de-archaeology and the ui/docs index landed in the earlier reorg
(0 "Phase N" refs in ui/docs/; 24 topic docs linked). This finishes the
sync: ui/README.md gains a finalized-web-target summary and links the new
topic docs (design-system, a11y, error-state-ux, pwa-strategy).
docs/ARCHITECTURE.md and docs/FUNCTIONAL.md need no change — they cover
the backend/gateway/cross-service contracts with no stale UI statements;
the finalized UI is client-local UX documented under ui/docs/. Marks F7
done.
