   curveTeaser.css — chat preview for the LA Curve product.
   Visual language is deliberately the SAME as the next_la chat (see
   next_la/src/exchange.css and the inline styles in LAexchange.jsx),
   even where it diverges from the rest of laready.co.uk. The whole
   block is scoped under .curve-chat-root so it doesn't leak.

   Step 3 (now): minimal scaffold styles only. Bubbles, chips, typing
   indicator and chart styles arrive in Step 4.
