/* =========================================================================
   MCP QUERY DEMO (#mcpQueryDemo).
   See src/components/McpQueryDemo.astro for the storyboard.
   Timeline: public/js/mcp-query-demo.js toggles `is-*` classes on the root.

   A single Claude-chat scene — the composer types a question, Claude
   replies citing a figure with an inline metric chip that flashes once.
   Same --xxx-* palette likeness rules as every other demo on the site,
   with a Claude-orange accent instead of the usual purple since this
   scene represents Claude's own interface, not Clive's.
