   Corporate -- structured support desk with guided options (PayPal / Bank of America style)
   A solid brand header, cards with an accent edge for the bot's messages and full-width option rows.
   Works with novichat.js (same ids and classes as novichatbot.css). Colors follow data-background-color
   (--main-color); everything else is a --novi-* variable below, so the look is easy to tweak.
   Full screen at 800px and narrower, like the other styles.
