   DipSkip — "Watch a strategy trade itself" live demo card
   ----------------------------------------------------------------------------
   An animated showcase: a DipScript runs in a mini editor (coloured exactly
   like the in-app Monaco editor) while a price chart streams left-to-right and
   the engine drops real buy/sell markers (the same arrowUp "B" / arrowDown "S"
   the DipSkip charts use) and books a running P&L.

   Desktop layout first. Tokens mirror the app:
