docs: design-dev accepted the SVOS retrofit — the /vor-ui brief is declined, and why

The ROADMAP row requiring a /vor-ui brief predates the IA doc. With that doc,
the landed templates and the seven handoff constraints, a /vor-ui pass would
have cost the operator a serial Q&A to re-derive IA already measured. design-dev
made that argument and it is better than the row it overrides.

Also settles: we merge and restart; he works against a copy, never :8090; the
concept round goes to the operator; webfonts by CDN link with display=swap,
because the CDN-free property turned out to be accreted rather than an
invariant (checked CLAUDE.md, the non-goals and the IA doc).

Corrects a memory defect in the same commit: a postbox send note is a
point-in-time snapshot and one was promoted into persistent memory as a durable
fact about a handle's delivery mode. It was wrong within the hour.

+  ⚠ **The `/vor-ui` brief this row used to require was DECLINED, and rightly.**
+  The row predates `docs/design/information-architecture.md`; with that doc, the
+  landed templates and the seven handoff constraints in hand, a `/vor-ui` pass
+  would have cost the operator a serial Q&A to re-derive IA we had already
+  measured — the exact operator-load this project exists to reduce. The handoff
+  message is the brief. If the design system ever wants the IA different,
+  design-dev raises it and we re-measure rather than either side guessing.
+
+  Settled with it: **we merge and restart** (the deployment root stays in one
+  pair of hands); design-dev works on `svos-retheme` in his own clone against a
+  COPY of `~/booth-data`, never touching `:8090`; a concept round goes to the
+  OPERATOR before any fixup. Webfonts arrive by Google Fonts `<link>` with
+  `display=swap` and a system fallback stack — the CDN-free property was
+  accreted, not an invariant, and self-hosting is a v1.1 item because
+  `v1.0.0b1` promises no new features.
