/* ============================================================
   FLUENTIAL WEALTH — COMPONENTS  v1.1
   ------------------------------------------------------------
   Requires tokens.css (and fonts.css for true typefaces).
   Everything below is token-driven and works in both themes.

   Breakpoints (px, used verbatim in media queries — CSS custom
   properties cannot parameterise @media):
     640   — phone → large phone / small tablet
     960   — tablet → desktop; nav collapses below this
     1200  — content max-width
   Keep these in sync with the `breakpoint` group in tokens.json.
