/* ==========================================================================
   Buzizi Foundation - Giving System (assets/giving.css)
   Shared stylesheet for /giving, /give-monthly, /mission, /contact, /thank-you.

   Built ON the existing design system (assets/tokens.css + assets/foundation.css).
   Every color, radius, font and easing below resolves to a --bf-* / --font-* /
   --ease-* token already defined there. No new fonts, no framework, no @import,
   no build step. Load AFTER foundation.css + spacing-fixes.css.
