   Friendse — FP UI Kit  (fp-ui-kit.css)
   --------------------------------------------------------------------------
   Site-wide design system: unique brand tokens, typography, buttons, inputs,
   cards, chips, and a modern mobile-first polish layer.

   IMPORTANT: this file does NOT hijack the existing theme system
   (friende-themes.css). Themes keep controlling --c-* variables. This file
   only ADDS a brand layer (--fp-*) plus shared components, so nothing that
   already works breaks.

   Load AFTER friende-themes.css.
