/* Convex Opportunities — design system (splash slice).
   ───────────────────────────────────────────────────────────────────────────
   This is the minimal slice of the Convex design system that the public splash
   (index.html) consumes: the self-hosted Marcellus display face, the brand
   tokens, and the Button / LinkWithIcon component classes. It replaces the
   former Google Fonts <link> and the bespoke button/link rules in styles.css,
   so the splash now renders from the same tokens and components as everything
   else in the system — with no third-party network call.

   Source of truth is .design-sync/ (the hand-authored @convex/ds package); the
   token + component blocks below are copied verbatim from the generated
   ds-bundle/ (tokens/*.css and _ds_bundle.css). Only Marcellus is shipped here
   — the splash uses no body text, so the Source Serif 4 reading face and the
   chart/letter/tearsheet styles are intentionally left out to keep this page
   lean. The --cvx-font-text/-num tokens are kept for parity but are inert here
   (no Source Serif @font-face is loaded). Regenerate from .design-sync/ if the
   button/link treatment changes upstream. */
