/* ============================================================
   Dan Sanderson — shared components
   ------------------------------------------------------------
   Static port of the design-system React components, whose CSS
   was previously injected at runtime. Markup is produced by the
   theme's PHP (template-parts + helper functions) using the
   same dsx-* class contract, so a button rendered by WordPress
   matches a <Button> from the design system 1:1.

   Source: Dan-Sanderson-design-system/design/components/**
   Depends on: tokens.css (custom properties only — no literals).
