/* The SDK card library lives outside this Next.js app's source tree.
   Tailwind 4's automatic source detection only scans the project
   root, so without an explicit ``@source`` directive the utility
   classes used inside ``samples/copilotkit/components/*.tsx`` get
   tree-shaken out of the generated CSS — colored severity pills
   silently flatten to plain text. Pin the path. */

/* shadcn/ui design tokens (Tailwind 4 syntax). The variables here come
   from `npx shadcn@latest add` with `baseColor: neutral` and match the
   conventions used across CopilotKit's own samples (research-canvas,
   travel, banking) so the cards feel native to the ecosystem.

   Brand accent for LayerLens Stratix is layered on top via Tailwind
   class strings (e.g. `bg-[#6766FC]`) at component sites — the same
   pattern research-canvas uses for its `#6766FC` indigo. */

/* CopilotChat token bridge.
   CopilotKit's chat widget reads its own ``--copilot-kit-*`` palette
   (see ``packages/react-ui/src/css/colors.css``). The semantics from
   that file:

     primary-color           = user message bubble + interactive accents
     contrast-color          = text on primary
     secondary-color         = assistant message / card background
     secondary-contrast-color= main content text on secondary
     background-color        = chat page background
     muted-color             = disabled / placeholder
     separator-color         = borders / dividers
     input-background-color  = textarea bg

   We map each onto the shadcn neutral token with the matching role
   so the chat feels native in both light and dark. Brand accent
   (#6766FC) is applied separately on actual CTA buttons via Tailwind
   classes — not by hijacking ``secondary-color``, which would make
   assistant messages render as solid indigo bubbles. */
