Design system

Design-token reconciliation and prototype status. For consumption rules see ../architecture/design-system-conventions.md; for the user-facing UI/UX overview see ../overview/ui-and-ux.md.

• tokens.md – Token reconciliation (legacy OterColors → Oter.* tokens), open decisions, mapping table
• loading-error-refresh.md – UiState<T>, which primitive to reach for, which failure gets which surface, and which screens have refresh (and why the rest don’t)
• prototype-implementation-status.md – Prototype implementation status
