   appointments_lite — design tokens and shared primitives.

   The palette, type scale and the flat, borderless-card look are taken from the
   reference build. That build shipped them as Tailwind utility classes compiled
   into a 46 KB stylesheet; here they are plain CSS custom properties and a
   handful of component classes, which is both smaller and legible in the markup
   without a Tailwind cheat sheet in the other hand.

   Fonts: Prata for display, Montserrat for the uppercase micro-labels, Ubuntu
   Light for body text — self-hosted from fonts/ (see css/fonts.css), with real
   fallback stacks so the page is still correctly proportioned before they land.
