/* Ryber landing page — layout and component CSS. The design system's own Card/Badge/
   Button live as JS web components (_ds_bundle.js) in the mockup authoring tool, not
   as reusable plain-CSS classes - this file implements the small set of visual
   patterns this one page actually uses, directly, per the handoff's own scope note
   not to adopt the full 27-component library speculatively. Tokens (colors,
   typography, spacing, radius, elevation) are the single source of truth for every
   value below - no hardcoded hex/px that duplicates what a token already names. */

   live: an earlier version of this file defined its own outline-based

   overrode entirely (confirmed via getComputedStyle: outline-style computed to
