   BotRouter cabinet — design system (replaces Bootstrap).
   Spec: docs/design/design-spec.md · Tokens: docs/design/tokens.json
   Archetype: neutral-functional. One blue accent. Borders-first. Light + dark.
   Class names mirror the ones the templates already used (Bootstrap-compatible
   subset) so bodies needed minimal edits — the look lives here.
