/* MC Assistant chat window. Everything is scoped under .mc-ai so the theme is not affected (and vice versa).
   Mind Center chat window. Fonts Lato (text) and Playfair Display (title), as on the site theme.
   Colours come from the Mind Center theme's own CSS variables (secondary blue and skin green), with #09B8E2 / #b4d251
   as fallbacks. Blue backgrounds carry WHITE, bold text with a soft shadow.
   White on the green is too faint (1.9:1), so the green button carries a navy icon. */
