Install ReUI (MCP, skill, @reui registry, Tailwind v4, shadcn base-nova) and move the shared UI onto it: Button, Tag, Check, Input/Textarea, Segmented, Alert, Panel, Dialog, Tooltip, Menu and Select (Popover), Toast (sonner), the Table frame (DataGrid), the Dashboard KPI strip, the shnt Ops palette, Geist and the type scale. Design only: behaviour, texts and roles are unchanged. Tests that asserted the old DOM were updated; the tests now format numbers in English wherever they run. docs/reui-migration-plan.md records the plan and its decisions.
