/* ============================================================================
   Kuduy component system — one language: shared typography, spacing, borders,
   radius, motion. Low-chrome, border-first, no build step. Every rule binds to
   a token from tokens.css; no magic colours, sizes, or durations live here.

   Principles applied throughout: borders over shadows, accent used only for
   wayfinding (links / focus / active state), motion subtle & fast, focus
   always visible, reduced-motion respected (bottom of file).
