   "Material You" / Material 3 Expressive, ported from the Lovable redesign.

   Every color is a tone derived from one seed hue (--seed-h), like Android
   dynamic color. Visitors can change the seed and light/dark mode from the
   palette button in the nav; components only use the role tokens below.
   Type: Google Sans Flex with the ROND axis for rounded, expressive headlines.
