/* =========================================================================
   AI CO-BUILDER CHAT DEMO (#aiCoBuilderChatDemo).
   Duplicate of BudgetDetailDemo — see src/components/AiCoBuilderChatDemo.astro
   for the storyboard.
   Timeline: public/js/ai-cobuilder-chat-demo.js toggles `is-*` classes and
   `data-cursor` on the root.

   Two full-width scenes crossfade (AI Co-Builder chat → bottom-up table)
   instead of a permanent chat/table split — same single-scene-at-a-time
   approach as the homepage hero demo (BudgetDemo), which is what makes
   this scale to any width, mobile included, with no per-breakpoint layout
   rework.

   The --acb-* palette mirrors the PRODUCT (webapp_v3 src/styles/_theme.scss),
   same likeness rules as the other demo components on this page.
